## Abstract When the density of nβbutyl branches in an ethyleneβhexene copolymer increases from 0 to 4.6 butyls/1000 C, the rate of slow crack growth decreases by a factor of 10^4^ . The activation energy for the process is nearly independent of branch density and is about 120 kJ/mol. It is the num

The effects of g-irradiation were measured in a HDPE and in the resin after it was recrystallized. The fracture mode of the initial material transformed from crazing to complete brittle failure at a critical dose. The failure mode of the recrystallized material transformed from crazing to shear defo
An optical microscopy study and a micro-Raman spectroscopy study were carried out on polyethylene samples subjected to an environmental stress crack resistance (ESCR) test. The aim was to elucidate the molecular deformation mechanisms associated with the failure process. It has been shown that in th
## Abstract Polyolefins, particularly polyethylene, are known to fail via crack initiation and crack propagation when exposed to multiaxial longβterm static stresses at elevated temperatures. Using concepts of linear elastic fracture mechanics, this article describes and discusses the effects of st
