Abstract

Exclusive formation of poly(ethylene-co-styrene)s were observed by introduction of ethylene into the solution of syndiospecific styrene polymerisation using Cp′TiCl2(O-2,6-iPr2C6H3) (Cp′ = 1,2,4-Me3C5H2, tert-BuC5H4)-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.
