摘要: 合成了一系列茂金属催化剂(C5H4R)2TiCl2[R=H(1),Me(2),C6H11(3)]和(C5H4R)2TiAr2[R=H,Ar=C6H5(4),p-MeC6H4(5),m-MeC6H4(6);R=Me,Ar=C6H5(7),p-MeC6H4(8);R=C6H11,Ar=C6H5(9),p-MeC6H4(10)],研究了这些催化剂对苯乙烯丁二烯嵌段共聚物SBS的催化加氢,考察了催化剂种类、用量及催化剂各组分之间的比例对加氢效果的影响,得到了较佳的条件,可使聚合物加氢度达到98以上,钛催化剂用量为0.001~0.003mmol/g聚合物.

Abstract: Aseries of titanocenes[(C5H4R)2TiCl2, R=H(1), Me(2), C6H11 (3) and (C5H4R)2TiAr2, R=H, Ar=C6H5(4), p MeC6H4(5), m MeC6H4(6); R=Me, Ar=C6H5(7), p-MeC6H4(8); R=C6H11 , Ar=C6H5(9), p-MeC6H4(10)] were synthesized. The catalytic hydrogenation of SBScopolymer using these catalysts was studied.The effects of the types of catalyst, the amount of catalyst and the component ratio of catalyst were investigated and found that the SBSwas hydrogenated more than98 when the amount of catalyst was 0.001-0.003 mmol/g polymer. Among the catalysts, the ptolyltitanocene were synthesized. The catalytic hydrogenation of SBScopolymer using these catalysts was studied.The effects of the types of catalyst, the amount of catalyst and the component ratio of catalyst were investigated and found that the SBSwas hydrogenated more than 98 when the amount of catalyst was 0.001-0.003 mmol/g polymer. Among the catalysts, the ptolyltitanocene 8 gives the best result and is a promising catalyst system for catalytic hydrogenation of SBScopolymer.
