FRACTURE STUDIES IN GLASSY POLYMERS

Abstract

The objective of the program was to study the fracture of glassy organic polymers so that a better understanding between the polymer structure and fracture characteristics could be gained. Of particular interest was the determination of the fracture surface work or energy required to initiate and propagate a crack through the polymer. Polymer structural features which were studied include (1) chain stiffness, conformation and molar cohesion, (2) degree of crosslinking, (3) tacticity and degree of crystallinity, (4) molecular weight and molecular weight distribution, and (5) polymer molecular orientation.
