Copolymerization of Butadiene and Isoprene by NdC_6H_6(AlCl_4)_3-AlR_3 System

摘要

This paper reported the copolymerization results of butadiene and isoprene catalyzed byNdC6H6（AlCl4）3-AlR3 system.The results show that the catalytic activity is dependent on the weight ratioof butadiene and isoprene,the concentration of comonomers,the nature of alkylaluminium and thepolymerization temperature as well.High contents of 1,4 microstructure of copolymer are obtained by thenovel catalyst system.
