在间规聚合反应体系中引入乙烯，在不产生间规聚苯乙烯的情况下，通过Cp‘TiCl(2)(O-2，6-(I)Pr(2)C(6)H(3))(Cp’=1，2，4-Me(3)C(5)H(2)，Tert-Buc(5)H(4))-MAO催化剂将乙烯引入到间规聚合的溶液中，观察到了专有的聚乙烯-共聚S的生成。
Exclusive formation of poly(ethylene-co-styrene)s were observed by introduction of ethylene into the solution of syndiospecific styrene polymerisation using Cp'TiCl(2)(O-2,6-(i)Pr(2)C(6)H(3)) (Cp' = 1,2,4-Me(3)C(5)H(2), tert-BuC(5)H(4))-MAO catalysts without by-production of syndiotactic polystyrene, whereas the styrene polymerisation did not proceed when ethylene was removed from the reaction mixture of ethylene/styrene copolymerisation.
