Available in PDF, EPUB and Kindle. Book excerpt: Polyurethane block copolymers were synthesized containing 33 and 50 wt% soft segment, and hard segment based on 4,4-diphenylmethane dissocyanate (MDI) chain extender. The soft segments were mixtures of poly(tetramethylene oxide) (PTMO) and poly(perfluoroalkylether) (PFEG) glycols (Mn=1000 and 1900, respectively), ranging from 4 to 100wt% PFEG. The PMTO polyol in one sample was substituted with a PMTO/ethylene oxide polyol (75:25 mole ratio) (Mn=1140). The MDEA-extended polymer was ionized using 1,3-propane sultone. The morphology, bulk, and surface properties of these polymers were evaluated by a variety of techniques. Differential scanning calorimetry and dynamic mechanical analysis showed that the incorporation of PFEG into the soft segment phase slightly enhanced the degree of phase separation.

Available in PDF, EPUB and Kindle. Book excerpt: "Polymer Science and Engineering: Challenges, Needs, and Opportunities," a report issued in 1981 by the National Research Council's ad hoc Panel on Polymer Science and Engineering gives ample support for the urgent need of increased commitment to basic studies on polymers. Needs and opportunities, mentioned in the Panel's list, included polymerization methods, specialty polymers, high performance materials, and in situ (reaction injection molding) polymerization for direct conversion of monomers/oligomers to useful shapes. Clearly, in all these and several other areas, advances in polymer synthesis are needed. Whether one takes a look at the commodity or specialty polymers area or considers areas of growing needs, such as polymers for the automotive, aerospace, electronics, communications, separations, packaging, biomedical, etc., advances in polymer synthesis are needed. Polymeric materials, as they are constantly being modified and improved, fine-tuned for current and additional needs, and more readily adopted by industry and the public, will have a vastly expanding influence on everyday life. However, lack of long-term support of meaningful size for basic research on all facets of polymer chemistry and engineering, with particular emphasis on making needed advances in polymer synthesis, could well stunt the growth of high techn.ology in our country. Expanding this thought, lack of attention to basic research on polymer synthesis could help foster or insure that we won't have materials with performance profiles to meet requirements of emerging technologies and national needs, in a reasonably economic and timely fashion.
Download or read book Functional Polyurethanes In Memory of Prof J zsef Karger Kocsis written by Sándor Kéki and published by MDPI. This book was released on 2020-04-01 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a collection of 22 per-reviewed scientific papers on the synthesis and characterization of polyurethanes with special chemical and physical properties. In our "plastic age", polyurethanes are one of the most versatile polymers with broad and excellent mechanical and chemical properties. These polyurethanes can be found in many areas of our every day`s life ranging from insulators through hard and soft foams to various biomedical devices. The huge number of possible variations in the types of reactants allows the scientists to design and tailor the properties of polyurethanes to specific needs. The fascinating chemistry and materials science of polyurethanes have attracted interests of many scientists. As a result, the progress in this field made by these scholars are summarized in this book with special emphasizes on the structure-property relationships and biomedical applications of polyurethanes as well as their environmental aspects are also highlighted in some papers. Thus, this collection of papers is recommended to all readers who are interested not only in the synthesis and properties of polyurethanes but want to be familiar with the theoretical description of their formation as well.

Download or read book Handbook of Thermoset Plastics written by Hanna Dodiuk and published by William Andrew. This book was released on 2013-11-28 with total page 795 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thermosetting plastics are a distinct category of plastics whose high performance, durability and reliability at high temperatures makes them suitable for specialty applications ranging from automotive and aerospace through to electronic packaging and consumer products (your melamine kitchen worktop is a thermoset resin!). Recent developments in thermoset plastics technology and processes has broadened their use exponentially over recent years, and these developments continue: in November 2011, French scientists created a new lightweight thermoset that is as strong and stable as previous materials yet can be easily reworked and reshaped when heated which makes it unique amongst thermosets and allows for repair and recycling. The Handbook of Thermoset Plastics, now in its Third edition, provides a comprehensive survey of the chemical processes, manufacturing techniques and design properties of each polymer, along with their applications. Written by a team of highly experienced practitioners, the practical implications of using thermoset plastics are presented – both their strengths and weaknesses. The data and descriptions presented here enable engineers, scientists and technicians to form judgments and take action on the basis of informed analysis. The aim of the book is to help the reader to make the right decision and take the correct action – avoiding the pitfalls the authors’ experience has uncovered. The new edition has been updated throughout to reflect current practice in manufacturing and processing, featuring: Case Studies to demonstrate how particular properties make different polymers suitable for different applications, as well as covering end-use and safety considerations A new chapter on using nanoparticles to enhance thermal and mechanical properties A new chapter describing new materials based on renewable resources (such as soy-based thermoset plastics) A new chapter covering recent developments and potential future technologies such as new catalysts for Controlled Radical Polymerization Goodman and Dodiuk-Kenig provide a comprehensive reference guide to the chemistry, manufacturing and applications of thermosets Updated to include recent developments in manufacturing – from biopolymers to nanocomposites Case Studies illustrate applications of key thermoset plastics
