| 摘 要： | <正> 脂肪族三烷氧基稀土化合物作为双烯烃定向聚合的主催化剂只有少数专利。最近,单成基等以Nd(OR)_(3-n)Cl_n-AlEt_3催化体系对双烯烃聚合进行了研究。三氯化钕醇合物与烷基铝组成的双烯烃聚合催化体系已有报导。本文着重研究一苯氧基二氯化钕四氢呋喃络合物和三氯化稀土酚合物与烷基铝组成的催化体系对丁二烯聚合的催化活性。

| Abstract: | C6H5ONdCl2 · nTHF (THF= n = 0, 1, 2) and NdCl3 · HOAr (HOAr =combined with aluminium alkyls are highly active for butadiene polymerization.In C6H5 ONdCl2 · nTHF-AlR3 system the activities increase with the increase in the coordination number of THF. In NdCl3 · HOAr-AlR3 the polymerization activities of variousphenols are in the following order:The polymerization rate is the first order with respect to the monomer concentration in C6H5ONdCl2 · 2THF-Ali-Bu2H. The plot of the conversion vs polymerization time is linear. The [n] of polymer decreases with the increase in the conversion of butadiene. |
