摘要：

Copolymerization of styrene (St) and isoprene (IP) with nickel(II) acetylacetonate [Ni(acac)(2)] and methylalumoxane (MAO) catalyst was investigated. It was found that the Ni(acac)(2)-MAO catalyst is effective for the copolymerization of St and IF. From the copolymerization of St (M(1)) and IF (M(2)) with the Ni (acac)(2)-methylalumoxane catalyst, the monomer-reactivity ratios were determined to be r(1) = 1,18 and r(2) = 0,88, i. e., ideal copolymerization was found to proceed to give perfectly random copolymers without formation of any homopolymer. The microstructure of IP units in the copolymers exhibits high cis-1,4 contents.
