Abstract

A model based on chain entanglements is developed to predict the molecular weight dependence of the fracture stress for brittle, amorphous polymers. It is then used in conjunction with the reptation model of polymer diffusion to predict the time and molecular weight dependence of the fracture stress in the closely related healing problem. Theoretical predications are found to be in close agreement with experimental data.
