✦ Synopsis

From a detailed analysis of poly[ethylene-co-( 1 -hexene)] obtained with typical metallocene catalysts, it was found that metallocene catalysts give two kinds of copolymers which differ in crystallinity. It may be thus plausible to assume that there are two kinds of active species in metallocene catalysts.
