Rheology modification of elastomers |
摘要 |
The present invention includes a process of preparing a coupled polymer comprising heating an admixture containing (1) at least one elastomer comprising ethylene and at least one comonomer which is selected from alpha olefins having at least 3 carbon atoms, dienes and combinations thereof 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 about 80 weight percent of the poly(sulfonyl azide) and sufficient to result in a coupled polymer having a gel content of less than about 2 weight percent.
