Abstract
PURPOSE: To improve the rubber processability of a chlorinated PE compsn., by mixing a chlorinated low-density PE having a high melt index with a chlorinated high-density PE having a low melt index in a specified ratio.
CONSTITUTION: The powder of low-density PE having a melt index of 0.2W10.0 and a density of 0.91W0.93 is subjected to an aq. suspension chlorination treatment at a temperature not lower than the melting point of its crystal so as not to leave PE crystals intact as much as possible, to produce a chlorinated PE having a chlorine content of 25W40wt%. The powder of high-density PE having a melt index of 0.01W0.4 and a density of 0.94W0.96 is subjected to an aq. suspension chlorination treatment at a sintering temperature of PE so as not to leave PE crystals intact as much as possible, until the chlorine content of PE becomes 30W50wt%. 50W90pts.wt. chlorinated low-density PE powder and 50W 10pts.wt. chlorinated high-density PE powder are mixed together to obtain the desired compsn.
