Abstract
975,877. Polymer blends. HERCULES POWDER CO. June 4, 1963 [June 15, 1962], No. 22152/63. Heading C3P. A polymer blend comprises stereoregular polypropylene and from 5 to 20% by weight of the polypropylene of an elastomeric copolymer of ethylene and propylene having a propylene content of from 30 to 60 mole per cent, a Mw/Mn ratio of less than 3, a solubility in n-heptane at -15‹C. of at least 93% by weight, a solubility in a mixture of equal volumes of n-heptane and acetone at 20 ‹C. of less than 6 % by weight and a reduced specific viscosity of at least 2À5. The elastomeric copolymer may be prepared by copolymerizing ethylene and propylene in a homogeneous liquid phase reaction mixture by passing ethylene and propylene into an inert liquid organic solvent having dissolved therein the copolymerization catalyst, at such a rate that the ratio of ethylene to propylene dissolved in the reaction mixture is kept constant throughout the polymerization reaction. The copolymerization catalyst is formed by mixing an organo aluminium halide with a vanadium compound VOY 3 where Y is a chloride, alkoxide or acetylacetonate group, the molar ratio of aluminium or vanadium being at least 10:1. Lists of catalyst components are given. The polymer blend may be formed by mixing the polypropylene and the elastomeric copolymer by known methods of mastication, such as mixing on hot rolls or in internal mixers such as a Banbury mixer. The mixing operation may be drastic enough to cause some thermal degradation of the polypropylene. The ethylene/propylene copolymer can be modified by copolymerization with a minor amount of a third monomer e.g. another α-olefine or a diolefine. Specification 856,736 is referred to.
