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.
