摘要: This invention relates to a method of making polymer blends using series reactors and metallocene catalyst. Monomers used by the are ethylene, higher alpha-olefin (propylene most preferred), optionally, non-conjugated diene (ethylidene norbornene, i.e., ENB, preferred). More specifically, this EP (ethylene-propylene) copolymers in which blend components differ any following characteristics: 1) composition, 2) molecular weight, 3) crystallinity. We use terminology copolymer also include terpolymers that contain varying amounts diene. Such commonly known as EPDM.
