    Abstract
  • A novel multifunctional macromolecular organolithium initiator (PD-Sn-(RLi) 3) was prepared via living anionic polymerization and used for the synthesis of miktoarm star copolymers in cyclohexane. The average molecular weight, polydispersity index, microstructure and unit composition of the miktoarm star copolymers were characterized with GPC and 1H-NMR. Performances of the miktoarm star styrene-butadiene rubbers were investigated in comparison with those of the blend rubbers such as the tin-coupled star-shaped random copolymers of styrene-butadiene rubber(S-SBR)/natural rubber (NR) blend rubber and S-SBR/ Cis-1, 4-polybutadiene rubber ( Cis-BR) blend rubber.
