浙江大学研究人员开发出一种气相聚合制备高反式聚异戊二烯的方法及其催化剂。该催化剂的组分包括第一组分过渡金属钒或钛的化合物、第二组分助催化剂、第三组分载体、第四组分纳米无机粒子。催化剂中,第一组分和第二组分的摩尔比为1:2~10,第一组分的摩尔量与第三组分的质量之比为1mol∶2000~200000g,第四组分和第三组分的质量比为1∶0.125~200。采用该发明催化剂气相 Zhejiang University researchers have developed a gas phase polymerization of high trans-polyisoprene method and its catalyst. The catalyst component comprises a first component vanadium or titanium transition metal compound, a second component cocatalyst, a third component carrier and a fourth component nano inorganic particles. In the catalyst, the molar ratio of the first component to the second component is 1: 2~10, the ratio of the molar amount of the first component to the mass of the third component is 1mol: 2000~200000g, the fourth component and the The mass ratio of the third component is 1: 0.125 ~ 200. The inventive catalyst gas phase is employed
