Abstract:
A process comprising (a) forming a polymeric admixture including at least one polyolefin having a molecular weight distribution less than about 3.5 which has been prepared using a single site catalyst and at least a crosslinking amount of at least one poly(sulfonyl azide) crosslinking agent; (b) shaping the resulting admixture; and (c) heating the resulting shaped admixture to a temperature at least the decomposition temperature of the crosslinking agent such that the crosslinking agent crosslinks the polymer admixture wherein the polymeric admixture crosslinked with a poly(sulfonyl azide) crosslinking agent has improved toughness and improved temperature resistance as measured by thermomechanical analysis (TMA) compared to the same polymeric admixture crosslinked with the same molar concentration of a peroxide crosslinking agent.
