POLYOLEFIN BLEND WITH THE HIGH ISOTACTIC INDEX AND TWO MELTING POINTS, USING AN OLEFIN POLYMERIZATION CATALYST OR A SUPPORTED CATALYST

摘要

PURPOSE: A polyolefin blend is provided to disperse the molecular weight with a small amount after being formed by polymerizing olefin.;CONSTITUTION: A polyolefin blend includes the isotactic index to the arrangement of olefin with the carbon number over 3 inside a polyolefin chain over 65%, the molecular weight distribution over 5, and two melting points. The polyolefin blend is produced by polymerizing the olefin under the presence of an olefin polymerization catalyst creating more than two catalyst active sites, and a carrier catalyst carrying the olefin polymerization catalyst inside a carrier, in one reactor.;COPYRIGHT KIPO 2010
