Samples of each of two high-density polyethylenes with various initial degrees of crystallinity, but otherwise identical, were exposed under a vacuum to moderate doses of gamma irradiation. The results indicate that, for otherwise initially identical polymer samples, the dose required to reach the g
Three low density polyethylenes, one long branched (A) and two linear (B and C), have been solid-stateextruded at several constant temperatures from ambient to 80Β°C and to draw ratios < 8. The initial densities and melt indices of A, B, and C are 0.920, 0.920, and 0.935 g/cm3, and 1.9, 0.8, and 1.2,
## Abstract It is well known that the addition of a small amount of highβpressure lowβdensity polyethylene (HPβLDPE) to linear lowβdensity polyethylene (LLDPE) can improve the optical properties of LLDPE, and LLDPE/HPβLDPE blend is widely applied to various uses in the field of film. The optical ha
