Abstract
The present invention is based on the discovery that diblock copolymers of ethylene and an atactic alpha-olefin that are prepared in the presence of a catalyst system comprising at least one metallocene compound and a non-coordinating anion are especially useful as compatibilizers with blends of polyethylene and isotactic poly-alpha-olefin homopolymers.
