The principal opportunity to synthesize isobutylene-block-butadiene or isobutylene-block-(butadiene-co-styrene) copolymers has been demonstrated. For this purpose, butadiene monomer or styrene-butadiene mixture were polymerized by anionic macroinitiator obtained by the reaction of alkali metals with the product of interaction between living cationic polyisobutylene active centres and 1,1-diphenylethylene. Some specific features of interaction between alkali metals and sterically hindered 1,1-diphenylalkylenes has been also discussed.
