Abstract
A microscopic model of cooperative motions in dense polymer systems is described. The mechanism suggested consists of collective replacements of molecular subsegments within closed loops of motion. Application of the model to the description of various effects related to mobility in dense polymer systems are presented. These include: (1) computer simulated “melting” of ordered chain structures as a method of generation of amorphous dense systems, (2) computer simulation of liquid-glass transition in polymer systems and (3) a qualitative analysis of chain motions in dense polymer systems.
