摘要：
An improved support vanadium catalyst, especially an improved Beran et al. catalyst system and ethylene polymerization process in which the improvement derives from fixing the promoter to a component of the catalyst composition such that it is a molecularly structural component of the catalyst and thus is not separately fed to the polymerization reaction, but instead is part of the catalyst composition fed to the reaction.
