| 摘要 |
<p>The invention includes a process of preparing a coupled polymer comprising heating an admixture containing: 1) at least one polyolefin comprising ethylene and at least one comonomer which is selected from alpha olefins having at least 3 carbon atoms, dienes and 2) a coupling amount of at least one poly(sulfonyl azide). The polyolefin is the product of polymerization of ethylene and at least one other alpha-olefin in the presence of a single site catalyst (transition metal like Va or Cr, metallocene or constrained geometry).</p> |
