Abstract:
A composition comprising a rheology modified, coupled polymer reaction product formed by heating an admixtures the admixture comprising (1) at least one polyolefin comprising ethylene and at least one comonomer which consist of alpha olefins comprising at least 3 carbon atoms, dienes and combinations thereof, wherein said polyolefin has a molecular weight distribution of less than or equal to about 3 and (2) a coupling amount of from 0.01 to about 5 weight percent of polymers in the admixture of 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 about 80 weight percent of the poly(sulfonyl azide) the phrase, wherein coupling is indicated by a viscosity change at a shear frequency of 0.1 rad/sec of greater than 5 perecent.
