Abstract of the Disclosure In the copolymerization of 4-methyl-1-pentene find at least one alpha olefin under batch polymerization conditions at a temperature of at least about 50°C wherein 4-methyl-1-pentene is initially polymerized in the absence of comonomer and then comonomer is added to the reaction vessel to permit copolymer formation, the improvement comprising initially forming 4-methyl-1-pentene homopolymer in an amount sufficient to reduce the solubility of the later formed copolymer at the polymerization temperature, said homopolymer being no more than about 5 weight percent of the end product copolymer. Also the products of such polymerizations are disclosed.
