"PROCESS TO PREPARE AN ENGAGED POLYMER, COMPOSITION, ARTICLE AND USE OF THE SAME". The invention includes a process for preparing a coupled polymer comprising heating a mixture 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). Polyolefin is the product of the polymerization of ethylene and at least one other alpha-olefin in the presence of a single local catalyst (transition metal such as Va or Cr, metallocene, or restricted geometry). |
