Rheology modification of polymers prepared using metallocenes |
摘要 |
Coupled polymers are prepared by a process comprising heating an admixture containing (1) at least one polyolefin comprising ethylene and optionally at least one comonomer and (2) a coupling amount at least one poly(sulfonyl azide) to at least the decomposition temperature of the poly(sulfonyl azide) for a period sufficient for decomposition of at least 80 weight percent of the poly(sulfonyl azide) and sufficient to result in a coupled polymer; particularly where the polyolefin is the product of polymerization of ethylene and optionally at least one other alpha-olefin in the presence of a single site catalyst.
