ABSTRACT:
A vinyl chloride polymer for providing a vinyl chloride paste which has a good thermal stability, a stability to sol viscosity and an excellent air release capability in the natural state or in a short period of time under a moderately low pressure is produced by using, in the production thereof, as an emulsifying agent, the alkali metal salts and/or ammonium salts of a mixture of a major amount of olefin alkyl sulfonates and a minor amount of hydroxyalkyl sulfonates (hereinafter olefin alkyl/hydroxyalkyl sulfonates) having from about 8 to 20 carbon atoms, in the polymerization thereof or in the preparation of a vinyl chloride paste from the polymerized product.
