Abstract

PURPOSE: The suspension polymerization of vinyl chloride in water is effected using a polyvinyl alcohol that is modified with unsaturated aliphatic monocarboxylic acid and thereby shows specific properties, to produce vinyl chloride polymer with uniform particle size and good gelation property.
CONSTITUTION: A polyvinyl alcohol modified with an unsaturated aliphatic monocarboxylic acid that has 300W2,500 average polymerization degree, 65W80mol% saponification degree, and over 60°C cloud point, when measured with 4% aqueous solution, is used as the suspension stabilizer and the suspension polymerization of vinyl chloride monomer in water is effected to produce said vinyl chloride polymer with uniform particle size and good gelation property.
