摘要： The instant invention relates to chlorinated poly ethylenes, method of producing the same, and articles made therefrom. The chlorinated polyethylene composition comprising the reaction product of (a) 55 to 90 percent by weight of a gas-phase high-density polyethylene, based on the total weight of the chlorinated high-density polyethylene, wherein the high-density polyethylene has a density in the range of 0.940 to 0.970 g/cm 3 , a melt index I 2 in the range of less than 15 g/10 minutes, a melt flow rate I 10 in the range of less than 200 g/10 minutes; and an average particle size in the range of less than 800 microns; (b) 10 to 45 percent by weight of chlorine, based on the total weight of the chlorinated high-density polyethylene; and (c) optionally less than 15 percent by weight of a surfactant, based on the total weight of the chlorinated polyethylene. The method of producing chlorinated high- density poly ethylenes according to the instant invention comprises the steps of (1) selecting a gas-phase high-density polyethylene, wherein the high-density polyethylene has a density in the range of 0.940 to 0.970 g/cm 3 , a melt index I 2 in the range of less than 15 g/10 minutes, a melt flow rate I10 in the range of less than 200 g/10 minutes, and an average particle size in the range of less than 800 microns; (2) selecting chlorine; (3) optionally selecting a surfactant; (4) forming an aqueous slurry of the high-density polyethylene optionally in the presence of the surfactant; (5) increasing the temperature of the slurry to a temperature of less than peak melting point temperature of the high-density polyethylene while agitating the high-density polyethylene; (6) admixing the chlorine with the slurry while maintaining the temperature of the mixture of chlorine and slurry at a temperature of less than peak melting point temperature of the high-density polyethylene while agitating the mixture; (7) optionally adding an anti-agglomeration agent; (8) thereby chlorinating the high-density polyethylene. The articles according to the instant invention comprise a chlorinated polyethylene composition comprising the reaction product of (a) 55 to 90 percent by weight of a gas-phase high-density polyethylene, based on the total weight of the chlorinated high-density polyethylene, wherein the high-density polyethylene has a density in the range of 0.940 to 0.970 g/cm 3 , a melt index I 2 in the range of less than 15 g/10 minutes, a melt flow rate I 10 in the range of less than 200 g/10 minutes, and an average particle size in the range of less than 800 microns; (b) 10 to 45 percent by weight of chlorine, based on the total weight of the chlorinated high-density polyethylene; and (c) optionally less than 15 percent by weight of a surfactant, based on the total weight of the chlorinated polyethylene.
