Abstract

The spatial dependence of dynamics in a series of polyolefins was investigated using molecular dynamics simulations. A crossover in dynamic behavior, which is characteristic of glass transition, was observed and it disappeared at high temperatures. The crossover was related to a shift from vibrational to relaxational motion, or a crossover from independent to cooperative dynamics. Results show that the spatial region characteristic of interchain packing is very important in interpreting polymer dynamics.
