Shear thinning ethylene/alpha-olefin interpolymers and their preparation

摘要

Shear-thinning ethylene/±-olefin and ethylene/±-olefin/diene monomer interpolymers that do not include a traditional branch-inducing monomer such as norbornadiene are prepared at an elevated temperature in an atmosphere that has little or no hydrogen using a constrained geometry complex catalyst and an activating cocatalyst.
