Available in PDF, EPUB and Kindle. Book excerpt: Tensile deformation of PMMA, extruded under hydrostatic pressure up to 4 kb has shown that the pressure-transmitting fluid (silicon oil) strongly affects the mechanical properties of this polymer. Unsealed specimens fractured in a brittle manner at almost the same strain of 5% in the whole pressure range examined, while specimens sealed with Teflon tape and rubber showed a brittle to ductile transition at only 0.25 kb. At this pressure, the craze initiation and shear band initiation stresses were found to become equal. The pressure dependency of the shear band initiation stress could be expressed well with a 'non-linear' pressure dependent Von Mises criterion and the onset of the shear banding was proved to relate to the enthalpy energy density stored in the specimen. The combination of the non-linear pressure dependent Von Mises criterion and the enthalpy energy density conept enable us to predict the pressure dependency of Young's modulus.

This book was released on 1968 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tensile tests were carried out on uniaxially oriented films of several amorphous linear polymers, i.e., polymethyl methacrylate, polystyrene, and poly-2, 2'-octamethylene-5, 5'-dibenzimidazole of different molecular weights. In the range of relatively high molecular weights, the latter were shown to have no direct effect on the mechanical properties of isotropic and oriented polymers. The mechanical properties were determined by the network structure formed during the extension, and by the average degree of orientation of the macromolecular mers. It was concluded that the formation of a particular structure is closely related to the molecular weight of a polymer, and that a given molecular weight can promote or hinder the formation of the corresponding structure under given extension conditions.

Available in PDF, EPUB and Kindle. Book excerpt: Emulsion Polymerization and Emulsion Polymers Edited by Peter A. Lovell Manchester Materials Science Centre, UMIST, Manchester, UK and Mohamed S. El-Aasser Emulsion Polymers Institute and Department of Chemical Engineering, Lehigh University, Bethlehem, PA, USA Emulsion polymerization is a technologically and commercially important reaction used to produce synthetic polymers and latexes for a wide range of applications. It is the basis of a massive global industry that is expanding due to the versatility of the reaction and the greater realization of the ability to control properties of the polymer latexes produced. Emulsion Polymerization and Emulsion Polymers provides an up-to-date treatment of both academic and industrial aspects of the subject in a single self-contained volume. Established knowledge is integrated with latest developments and introductory chapters to give a state-of-the-art summary which is also suitable as a broad based introduction to the field. The individual chapters have been written by specialists from academia and industry and are presented in a way which ensures that the book will be of equal value to experienced researchers and students.

This book was released on 2006 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The mechanical behavior of amorphous thermoplastics, such as poly(methyl methacrylate) (PMMA), strongly depends on temperature and strain rate. Understanding these dependencies is critical for many polymer processing applications and in particular, for those occurring near the glass transition temperature, such as hot embossing. In this thesis, the large strain mechanical behavior of PMMA is investigated using uniaxial and plane strain compression tests at varying temperatures and strain rates. This study captures both the temperature and rate of deformation dependence of PMMA, and correlates well to previous experimental work found in the literature for similar temperatures and strain rates. Additional work investigates the temperature change of the polymer specimens while the specimens are deformed at the glass transition, and the results to this study correlate well to those done at lower temperatures. Aside from experimental characterization of PMMA, a three-dimensional constitutive model previously used to describe the mechanical behavior of another amorphous polymer, poly(ethylene terephthalate)-glycol (PETG), is applied to model the observed mechanical behavior of PMMA. A comparison with the experimental data reveals that the model is able to successfully capture the observed stress-strain behavior, including the initial elastic modulus, flow stress, initial strain hardening, and the dramatic strain hardening behavior. In general, the model captures the temperature and rate dependence of PMMA in both uniaxial and plane strain compression. Elastic and Neo-Hookean material models were used in an initial 2-D study of embossing a polymer substrate with a rigid stamp. The results of this study show that a complex and accurate material model is necessary to obtain good numerical results using finite element analysis, since the results using the two different material models yielded different numerical results. Future work will further develop the finite element simulations into 2-D and 3-D models that optimize and simulate the embossing process using the constitutive material model.
