| 摘 要： | 本文考察了MoCl_4OC_8H_(17)-(i-Bu)_2Alo催化体系在加氢汽油中催化丁二烯聚合过程中的链转移情况,提出了比较聚合体系中各组分对链转移的贡献大小的方法和计算链转移次数的公式及链转移次数与聚合温度的函数关系式。发现本体系中单体和主催化剂是主要的链转移剂,向烷基铝的链转移占10％,向杂质的链转移仅占6％。在链转移反应中,单体和主催化剂的级数为1,烷基铝的级数为1/2。

| Abstract: | Investigation on the chain transfer in the polymerization of butadiene with MoCl4OC6 H17-(i-Bu)2AlO as catalyst has been carried out. In this catalyst system it was foundthat the monomer and MoCl4OC8H17 played a main part in the chain transfer. The rate of transfer is first order with respect to the concentration of both monomer and MoCl4OC8H17 and 1/2 order with respect to the concentration of the aluminium alkyl. |
