Abstract:
     The cyclized cis-1,4 butadiene-isopentadiene random copolymer is prepared by cyclizing modification reaction of conjugated dialkene copolymer. Rare-earth catalyst is used to synthesize the random copolymer whose both monomers are high cis-1,4 structure. In cyclizing reaction, aluminium alkylogen-halohydrocarbon system is used to make two monomer's link take part in cyclizing.
