摘　　要：研究了负载钛催化1-己烯(He)聚合的规律,考察了聚合条件对转化率和聚合物性能的影响。结果表明:以MgCl2为载体的负载钛高效催化剂体系催化合成的聚1-己烯(PHe)为高相对分子质量、无定型、透明的弹性体;较适宜的合成条件是Ti/He(摩尔比)为(3～5)×10-5,Al/Ti(摩尔比)为250～300,温度为30℃;氢气压力是调节相对分子质量的有效手段,随着氢气压力的不断增加,聚合物的相对分子质量急剧下降。The rule of polymerization of 1-hexene with supported titanium catalyst were researched. The effects of polymerization condition on conversion and properties of poly （1-hexene） were studied. The results showed that the polymer synthesized with supported titanium catalyst was high relative molecular mass, amorphous, transparent elastomer. The optimum polymerization conditions were mole ratio of Ti/He （3 -5）×10^-5, mole ratio of Al/Ti 250 300 at 30℃. The relative molecular mass was effected drastically by H2 pressure.
