Functional polyisoprene stars were prepared by copolymerization of polyisoprenyl lithium with divinylbenzene in n-heptane, where the polyisoprene arm was prepared by anionic polymerization using [2-[N,N-dimethylamino)methyl]phenyl]lithium as the initiator. The star polymer was removed from the unreacted arms. These functional stars were converted by quaternization with p-chloromethylstyrene into polyisoprene star-shaped macromonomers having ca. one vinylbenzyl group at each arm end.
