Popis:	Bisupport for the olefin polymerization was prepared by the gelation of the colloidal phase of SiCO2 using MgCl2 solution as an initiator. The prepared Ziegler-Natta/Metallocene hybrid catalysts on the bisupport exhibited the characteristics of both Ziegler-Natta and metallocene catalysts. The polyethylene produced by the hybrid catalysts showed two melting temperatures and a bimodal MWD, suggesting that the polymer was composed of two different lamella structures that were polymerized by each catalyst.
