PURPOSE:To provide the titled compsn. giving molding which are excellent in flexibility, moldability and resistance to heat and weather and has high dimensional accuracy, consisting of chlorinated PE, low-density PE and low-molecular PE. CONSTITUTION:0.01-15pts.wt. low-molecular PE having an MW of 300-10,000 a softening point of 50-140 deg.C and a specific gravity of 0.85-1.00 and optionally not more than 5pts.wt. nucleating agent such as a metal salt of stearic acid and not more than 10pts.wt. stailizer such as calcium stearate are blended with 100pts.wt. of the combined quantity of 99-70wt% chlorinated PE(A) having a density of 0.910-0.970g/cm<3>, an MW of 50,000-70,000 and a chlorine content of 20-50wt% and 1-30wt% low-density PE(B) having adensity of 0.900-0.930g/ cm<3>, a m.p. of 106-130 deg.C, an MI of 0.01-100g/10min as measured at 190 deg.C under a load of 2.16kg according to JIS K-6760 and contg. 3-35C1-C10 alkyl groups on side chains per 1,000 carbon atoms of its main chain. |
