Abstract
Crystallization behavior and spherulitic structure of linear high-density p olyethylene (HDPE), after being irradiated in its molten state by gamma -ra ys, was investigated by small-angle laser scattering (SALS) and differentia l scanning calorimetry (DSC). Significant changes in the crystallization of HDPE during cooling in air before and after being irradiated in the melt w ere observed. A critical minimum average molar mass between cross-links (20 0 carbon-carbon bonds) for spherulite formation in such an irradiated HDPE network was obtained.
