Abstract
PURPOSE: To prepare a vinyl chloride resin having a low initial sol viscosity and improved stability with time, by initiating polymerization of vinyl chloride, etc. in the presence of an anionic emulsifier, adding a polyoxyethylene alkylphenyl ether to the system and continuously carrying out polymerization.
CONSTITUTION: Homopolymerization of vinyl chloride monomer or its copolymerization with the other ethylenic unsaturated monomers (e.g. vinyl acetate, etc.) is initiated in the presence of an anionic emulsifier (e.g. sodium lauryl sulfate, etc.) (≥0.1 parts by weight on the basis of 100 parts by weight of the monomers). A polyoxyethylene alkylphenyl ether (≥0.1 parts by weight on the basis of 100 parts by weight of the nomomers) is added to the polymerization system in a lump, intermittently or continuously from the polymerization intiation to the stage when the polymerization conversion reaches 80%, and the polymerization is continued to give the desired resin.
