Since the highly active metallocene catalysts have successful opened up the possibility to synthesize norbornene-ethylene copolymer as a typical representative of the cyclic-olefins copolymer

copolymerization of norbornene with other α-olefin such as propylene is also paid more attention by the academics and industries. In this paper

the research progress of norbornene and propylene copolymerization in recent years is briefly introduced

including the copolymerization characteristics catalyzed by a variety of different structures metallocene catalysts and the structure analysis of the resultant copolymers. For the C2-symmetric and Cs-symmetric metallocene catalyst

the chain transfer reaction of norbornene and propylene copolymerization leads to low catalytic activity and low molecular weight of the obtained products. With the contrained geometry metallocene ansa-dimethylsilylene(fluorenyl)(amido)dimethyltitanium-based derivatives catalyzing copolymerization of norbornene and propylene

catalytic activity can be up to 107 g polymer·(mol cat·h)-1

and the resulting copolymer with a molecular weight of more than 200000

a norbornene content of up to 70% (mol) and high glass transition temperature can be obtained.
