摘　　要：分别以聚（苯乙烯－丙烯酰胺）（ＳＡＡ）和聚（乙烯－丙烯酸）（ＥＡＣ）为载体，合成了两类聚合物载体钛系催化剂。利用红外光谱（ＩＲ）、Ｘ射线电子能谱（ＸＰＳ）分析了载体与ＴｉＣｌ４的结合方式。Two types polymer supported titanium catalysts, TiCl 4/SAA and TiCl 4/EAC, have been synthesized, where poly(styrene acrylamide) and poly(ethylene acrylic acid) were used as carriers respectively. The infrared and X ray photoelectron spectra of TiCl 4/SAA suggest that the polymer supported catalyst possesses the structure C Ti←O R CH 2 . Ethylene polymerization with these catalysts have been investigated.
