| Abstract: | Three-arm star-shaped hydroxyl-terminated polybutadiene has been synthesized by means of anionic polymerization,using alkyllithium containing silicon-protected hydroxyl group as initiator and cyclohexane as solvent.Molecule weight and molecule weight distribution,the degree of branching,average functionality and main-chain microstructure were characterized by GPC and 1H-NMR.The results show that three-arm star-shaped hydroxyl-terminated polybutadiene via anionic polymerization has narrow molecular weight di... |
