Abstract
The molecular mechanisms of both large strain plastic deformation and those encountered in internal friction in flexible chain glassy polymers have remained controversial at best. While many ad-hoc mechanisms of imagined molecular conformational changes have been advanced and have proved to be very useful as kinetical scaling laws, there has been considerable skepticism on their validity. To remove this controversy we have performed detailed computer simulations of such deformation on bona-fide molecular structural models of glassy polypropylene (PP) and on bisphenol-A polycarbonate (PC) which we have newly determined. Here we report the results of these simulations.
