摘　　要：首次采用3种新型脂醚类化合物作为内给电子体合成催化剂用于丙烯聚合。对催化剂进行了红外光谱、XPS能谱测试表征和丙烯聚合研究,丙烯聚合结果表明Do-3效果最好,以DCPDMS为外给电子体时活性为31.4 kg/(g·h),等规指数为96.1%,熔体流动速率为15.5 g/10min。We first used tree novel donors to prepare polypropylene catalyst for propylene polymerization. The catalysts werestudied by IR, XPS and propylene polymerization. The results of polymerization showed that Do-3 compounds as donor was the best,when using DCPDMS as external donor the activity of the catalyst was 31.4 kgPP/g·cat·h, II of polymer was 96.1%, and MFR ofpolymer was 15.5 g/10min.
