用配位催化剂对丁二烯(Bd)与异戊二烯(Ip)进行共聚合已有较多报道,但关于共聚合对分子结构和结晶性能的影响的报道则甚少。本工作用LnCl_3-(C_2H_5)—OH-Al(C_2H_5)_3或Ln(naph)_3-Al(i-C_4H_9)_3-Al(C_2H_5)_2Br(简称为稀土)、Ni(naph)_2-BF_3(C_2H_5)_2O-Al(i-
There have been many reports on the copolymerization of butadiene (Bd) and isoprene (Ip) with coordination catalysts. However, little is reported about the influence of copolymerization on molecular structure and crystallization performance. In this work, LnCl_3- (C_2H_5) -OH-Al (C_2H_5) _3 or Ln (naph) _3-Al (i_C_4H_9) _3-Al (C_2H_5) _2Br C_2H_5) _2O-Al (i-
