This book was released on 2012-12-06 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1 957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 28 (thesis year 1 983) a total of 10,661 theses titles from 26 Canadian and 197 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 28 reports theses submitted in-1983, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

Available in PDF, EPUB and Kindle. Book excerpt: In 1974, as we approached the National Bicentennial and the Centenary of the American Chemical Society, Professor Otto Vogl, then Chairman of the Division of Polymer Chemistry, arranged a very special symposium dedicated to a review of the history of the Divi sion. It was an extraordinary occasion which included remarks by Professors Herman Mark, Charles Marvel, William Bailey, and Charles Overberger, all past Chairmen of the Division. The Executive Committee of the Division of Polymer Chemistry felt that 1976 deserved even more attention since it was to be also the 25th, the Silver Anniversary, of the Division of Polymer Chemis try. This year would be a most appropriate one not only to review milestones in our discipline, but also to look to the future. It was decided to undertake this volume and Dr. R. D. Ulrich agreed to serve as editor in assembling the collected papers. It is the hope of the officers of the Division that this volume will serve many purposes - a reference text, a record, and a source of perspective. F. E.

Available in PDF, EPUB and Kindle. Book excerpt: "The three main goals of this project are to determine the molecular weight dependence of polyethylene oxide) on the 1) morphology of crystalline material, as seen with the polarizing light microscope, 2) nucleation of the crystalline phase, as demonstrated with an annealing study, and 3) parameters of a mathematical model for crystallization kinetics. Bulk crystallization kinetics of polyethylene oxide) from the melt have been studied for a large molecular weight range, 1500 g/mol to 7,000,000 g/mol. The effects of molecular weight and cooling rate on the width and degree of supercooling of DSC crystallization exotherms have been studied to determine the type of nucleation involved and to determine the relationship between the DSC signals and the morphology of a crystalline sample. As the molecular weight increases, at a cooling rate of twenty degrees per minute, the width-at-half- height of the exothermic DSC peak decreases from seven degrees to approximately three degrees for the low molecular weight samples and increases from three to seven degrees for the high molecular weight samples. The degree of supercooling at which the peaks reach a maximum generally increases from twelve degrees Celsius to above twenty degrees Celsius. The slower the cooling rate the narrower the width at half height of the crystallization peak and the lower the degree of supercooling at the maximum point of the crystallization exotherms. For all of the molecular weight samples, the crystallization peak temperatures increase in the range of one to ten degrees of supercooling from a one-degree-per-minute cooling rate to a twenty degrees-per-minute cooling rate. The average width-at-half-height increases from three to six- degrees Celsius from the one degree-per-minute cooling rate experiment to the twenty degreesper- minute cooling rate experiment. The morphology of the samples varied from a coarse non-interconnected lamellae formation below the critical molecular weight to an interconnected lamellae formation, also known as a spherulite, above the critical molecular weight. The critical molecular weight for polyethylene oxide) is 3400 g/mol. Based on the expression for the linear crystal growth rate, reported by Cheng et al.1, a mathematical model was created to model the DSC crystallization curves. This model, which incorporates heat transfer effects, can model the width and shape of the DSC curves, but the degree of supercooling that the model predicts is generally smaller than the experimental degree of supercooling. While modeling the DSC crystallization curves, it was found that the activation energy for reptation motion, U*, has less of an effect on the model crystallization curves than does the surface energy term, Kg, of the Cheng growth rate expression."--Abstract.

Download or read book Polyolefin Compounds and Materials written by Mariam Al-Ali AlMa'adeed and published by Springer. This book was released on 2015-12-23 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes industrial applications of polyolefins from the researchers' perspective. Polyolefins constitute today arguably the most important class of polymers and polymeric materials for widespread industrial applications. This book summarizes the present state of the art. Starting from fundamental aspects, such as the polymerization techniques to synthesize polyolefins, the book introduces the topic. Basic knowledge about polyolefin composites and blends is explained, before applications aspects in different industry sectors are discussed. The spectrum comprises a wide range of applications and industry sectors, such as the packaging and food industry, the textile industry, automotive and buildings, and even biomedical applications. Topics, which are addressed in the various chapters, comprise synthesis and processing of the materials; their classification; mechanical, physical and technical requirements and properties; their characterization; and many more. In the end of the book, even the disposal, degradation and recycling of polyolefins are addressed, and light is shed on their commercial significance and economic value. In this way, the book follows the entire 'lifetime' of polyolefin compounds and materials: from their synthesis and processing, over applications, to the recycling and reuse of disposed or degraded polyolefin substrates.
Download or read book Polymer Crystallization written by Günter Reiter and published by Springer. This book was released on 2008-01-11 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: The classical view on polymer crystallization basically focused on the expla- tion of a few macroscopically observable parameters like the thickness of the resulting lamellar structure and the corresponding growth rates. However, the emerging paradigm for the description of chain crystals is too simple and cannot account for the complex non-equilibrium processes responsible for structure f- mation on various levels, ranging from the nanometer up to the millimeter scale. This complexity detected by several novel experimental results led to a renewed interest in this ”old” topic of polymer crystallization. These new ?ndings c- cern the early stages of the crystallization process, crystal formation in con?ned geometries like ultra-thin ?lms and the competition between (micro)phase s- aration and crystallization in copolymers and blends. In particular, high spatial resolution techniques such as atomic force microscopy provided deeper insight into the molecular organization of crystallizable polymers. Computer simu- tions based on microscopic processes were used to improve our understanding of how polymer crystals are nucleated and how they grow. New ideas emerged about possible multistage pathways which are followed during the formation of polymer lamellae. The importance and the consequences of the non-equilibrium character of polymer crystals got signi?cantly more attention. Links and ana- gies to growth phenomena and pattern formation in general are being developed. However, these ideas are still subject of intensive and controversial discussions.
