COPOLYMERIZATION OF ETHYLENE WITH HEXENE BY POROUS POLYMER SUPPORTED ZIRCONOCENE

摘要

@@Metallocene catalysts gained widespread importance for polymerization of olefins on account of their high activity and versatility1. They allow one, for example to control tacticity and to incorporate discrete ratios of comonomers. In order to carry out polymerization in slurry, the metallocene have to be supported. Traditional supports, such as high surface area silica or alumina, have received the most attention. Such acidic supports, however, have reactive surfaces that can lead to catalyst deactivation and thus alternate supports are desirable.
