专利汇可以提供Production of vinyl chloride polymer专利检索,专利查询,专利分析的服务。并且PURPOSE: Chlorinated polyolefin is previously swollen by a water-soluble organic compound and then dispersed in an aqueous medium preferably containing oxygen and a surface active agent. Further vinyl chloride monomer is fed and polymerized to produce title polymer with high impact strength.
CONSTITUTION: A chlorinated polyolefin is previously swollen by a water-soluble organic solvent as methanol, ethanol or isopropanol and then dispersed in aqueous dispersion containing oxygen with a partial pressure of 3W30 mmHg and at least one surface active agent selected from the group consisting of polyoxyethylenealkyl phenyl ethers, alkylsulfate salts, alkylsulfosuccinate salts and alkylarylsulfate ester salts. Then vinyl chloride is fed and polymerized in the presenc of a radical catalyst to produce said polymer.
