摘　　要：以氯化三苯基膦铑为催化剂，对丁二烯－ｂ－甲基丙烯酸甲酯共聚物的催化加氢反应进行了研究，用ＮＭＲ、ＦＴＩＲ、动态粘弹谱和化学分析法对加氢产物进行了表征。证明ＲｈＣｌ［Ｐ（Ｃ６Ｈ５）３］３可有效地使共聚物中的Ｃ＝Ｃ加氢，且具有很高的选择性，未加氢的双键含量小于０．７１％。This paper studies catalytic hydrogenation of C=Cin poly(butadiene-b-methyl methacrylate) copolymer by using RhCl[P(C6H5)3]3 as the catalyst.The results which come from the IR,NMR,DMA and chemical analysis demonstrate that RhCl[P(C6H5)3]3 is an ef-ficient catalyst in homogeneous catalytic hydrogenation,and the reaction possesses excellent selectivity.The catalyst provides quantitative hydrogenation of C=C unsaturation without any hydrogenation of the ester functionality. After completely hydrogenated,the weight percentage of unreduced C=C is less than 0.71%.
