Abstract:
A composition comprising a blend of polyethylene and an isotactic poly-alpha-olefin homopolymer, together with a diblock copolymer compatibilizer of polyethylene block and an atactic poly-alpha-olefin block having no melting point, said isotactic poly-alpha-olefin homopolymer and said atactic poly-alpha-olefin block having the same monomer units, said diblock copolymer compatibilizer being formed by sequentially polymerizing ethylene and alpha-olefin in the presence of at least one metallocene compound and a non-coordinating anion, and the diblock copolymer having terminal unsaturation, at least 30% of which is vinylidene unsaturation.
