摘要: Novel metallated polyolefins are produced by contacting a polyolefin having a vinylidene group in the terminal portion with organoalkali metal compound in the presence of alkali metal t-alkoxide or tertiary amine. The metallated polyolefin is used to initiate the polymerization of polymerizable monomers to produce block copolymers of at least two blocks, at least one of which is saturated polyolefin.
