| Research Abstract |
ansa-Dimethylsilylene(fluorenyl)(tert-butylamido)dimethyltitanium complex and its derivatives were found to be an excellent catalyst for copolymerization of norbornene and 1-alkene when combined with a suitable cocatalyst. The glass transition temperature of the produced polymer was widely controlled by the comonomer composition up to 400℃. The catalytic system conducted living copolymerization combined with a suitable cocatalyst, which enable us to synthesize tailor-made polymers composed of norbornene and 1-alkene.
