摘要： A process for producing a 4-methylpentene-1 copolymer comprising copolymerizing 4-methylpentene-1 with other .alpha.-olefin in a hydrocarbon solvent in the presence of a Ziegler-Natta catalyst and a resin composition containing the 4-methylpentene-1 copolymer are disclosed. The copolymerization comprises a first stage in which (A) a homopolymer or random copolymer of 4-methylpentene-1 having an .alpha.-olefin content of not more than 3 mol % and an intrinsic viscosity of at least 2.5 dl/g is prepared and a second stage in which (B) a random copolymer having an .alpha.-olefin content higher than that of the polymer (A) and no higher than 9 mol % and an intrinsic viscosity of at least 2.5 dl/g is prepared, and the produced copolymer insoluble in the solvent is separated to recover a 4-methylpentene-1 copolymer containing from 5 to 80% by weight of the polymer (A). The process produces a solvent-insoluble copolymer in an increased yield without impairing transparency of the copolymer.

摘要： A process for producing propylene-ethylene block copolymers by a three-step polymerization technique using a stereoregular catalyst, characterized in that the first-step polymerization is carried out by supplying propylene alone or a propylene/ethylene mixture so that the ethylene/propylene reaction ratio is 6/94 or less, thereby polymerizing 60 to 95% by weight of the total polymerization amount, the second-step polymerization is carried out by supplying a propylene/ethylene mixture so that the ethylene/propylene reaction ratio is 15/85 to 79/21, thereby polymerizing 1 to 20% by weight of the total polymerization amount, and the third-step polymerization is carried out by supplying a propylene/ethylene mixture so that the ethylene/propylene reaction ratio is 50/50 to 89/11, thereby polymerizing 4 to 35% by weight of the total polymerization amount, with the ethylene/propylene reaction ratio in the third step made larger than that in the second step. Said process can give propylene-ethylene block copolymers markedly well balanced in impact strength, stiffness, transparency and impact blushing.
