Dendritic ethylene polymers and processes for making

摘要

Provided is a dendritic ethylene polymer. The polymer is a dendritic polymer of an ethylene/alpha-olefin-diene copolymer and a vinyl-terminated polyethylene. There is also provided a process for making a dendritic ethylene polymer. The process includes the steps of preparing a dendritic ethylene polymer by reacting ethylene/alpha-olefin-diene copolymer with vinyl-terminated polyethylene in the presence of a radical source. There is also provided a blend and a blown film that include the dendritic ethylene polymer.
