An ethylene-hexene copolymer was fractionated into five fractions and the density of shortchain branches was measured for each fraction. The slow crack growth behavior was measured on each fraction by sandwiching the small amount of fractionated resin of about 0.2 g between polyethylene grips. The r
The following theoretical equation was obtained for the rate of initiation 6 of slow crack growth in polyethylene: where tr = applied stress, K = stress intensity, 7 = Poisson's ratio, E = Young's modulus, trc = stress to produce a craze, try = yield point, d = primordial thickness of the craze and
