Abstract
PURPOSE: To obtain a vinyl compound emulsion having viscosity of small temperature dependance and high structural viscosity index, by the emulsification of a vinyl compound, using a specified polyvinyl alcohol as an emulsifier.
CONSTITUTION: In the emulsion polymerization of a vinyl compound, a polyvinyl alcohol resin of average saponification degree of 85mol%, 4% aqueous solution of which has a cloud point ≥90°C, is used as an emulsifier. Preferred polyvinyl alcohol resin is that contg. a cloud point eliminator such as a surface active agent in a polyvinyl alcohol having >90°C cloud point, or that obtd. by intreducing ionic functional groups into polyvinyl alcohol etc. Preferred vinyl compound is vinyl acetate, (meth)acrylate, vinyl chloride, styrene, ethylene, etc.
