HIGH DENSITY POLYETHYLENE HAVING A BRIDGE STRUCTURE WITH EXCELLENT MECHANICAL PROPERTY AND THERMAL STABILITY AND A PREPARATION METHOD THEREOF

摘要

PURPOSE: A high density polyethylene having a bridge structure with excellent mechanical property and thermal stability is provided to control melting elasticity and to obtain a HDPE with excellent rigidity and workability.;CONSTITUTION: A high density polyethylene having a bridge structure is bonded by performing radical reaction of a silane compound represented by chemical formula 1 with a high density linear polyethylene with a double bond at the end of a main chain. The high density linear polyethylene has 1 - 15 double bond per carbon 1000 present in the high density linear polyethylene and is produced by a Philips polimerization method using a chrome catalyst.;COPYRIGHT KIPO 2010
