PURPOSE:To provide the subject composition having no problem on compression permanent strain and permanent set and useful for rubber wires, rubber cables, rubber mats, etc., by adding PP and an active group-containing liquid polybutadiene rubber to a gel-containing chlorinated PE in specific ratios. CONSTITUTION:The objective composition contains (A) 100 pts.wt. of chlorinated PE (preferably having a chlorine content of 15-55wt.%) containing a gel content of >=20wt.%, (B) 5-50 pts.wt., preferably 10-40 pts.wt., of PP (preferably having a melt flow index of 0.1-30g/10min) and (C) 3-20 pts.wt. of a liquid butadiene rubber (preferably having a number-average mol.wt. of 200-4000) having active groups (e.g. OH, COOH, NCO, epoxy, amino groups, etc.). |
