摘　　要：综述了以乙烯为唯一单体制备线性低密度聚乙烯的多米诺催化体系,按照催化方式的不同,分别介绍了齐聚主催化剂/共聚主催化剂/助催化剂体系、主催化剂/齐聚助催化剂/共聚助催化剂体系两大类型,其中按照不同类型主催化剂的组合进行了分类。着重阐述了各类乙烯多米诺催化体系的特点、制备的聚合物的特征及乙烯多米诺催化的优缺点等。The progress in preparation of linear low density polyethylene by tandem catalysis of ethylene was reviewed. According to the type of catalyse, the catalytic systems of oligomerization catalyst/copolymerization catalyst/cocatalyst and catalyst/oli-gomerization cocatalyst/copolymerization cocatalyst were introduced respectively. According to the difference in catalyst, the catalyst combination were classified. Properties of these catalytic systems and polymer obtained were stated emphatically.
