IMPACT RESISTANT GLASSY POLYMERS: PRE-STRESS AND MODE II FRACTURE FEBRUARY 2013 JARED STEVEN ARCHER B.S., WESTERN WASHINGTON UNIVERSITY M.S., UNIVERSITY OF MASSACHUSETTS AMHERST Ph.D., UNIVERSITY OF MASSACHUSETTS AMHERST Directed by: Professor Alan J. Lesser Model glassy polymers, polymethyl methacrylate (PMMA) and polycarbonate (PC) are used to experimentally probe several aspects of polymer f...

We review recent results from computer simulation studies of polymer glasses, from chain dynamics around glass transition temperature Tg to the mechanical behaviour below Tg. These results clearly show that modern computer simulations are able to address and give clear answers to some important issues in the field, in spite of the obvious limitations in terms of length and time scales. In the p...

Abstract The review considers the possibilities of new methods solid-state extrusion polymers based on use deformation schemes that include simple shear - equal-channel angular extrusion, multi-angle and combined extrusion. Information evolution physico-mechanical properties glassy, semi-crystalline polymers, polymer blends composites is given.

For the past few decades, researchers have been intrigued by glassy polymers, which applications ranging from gas separations to corrosion protection drug delivery systems. The techniques employed examine sorption and diffusion of small molecules in polymers are subject this review. Diffusion models regulated Fickian non-Fickian diffusion, with being more prevalent. characteristics determined i...
