An aqueous solution of partially hydrolyzed vinyl ester resin having an excellent stability and useful particularly as a secondary agent for suspension polymerization of vinyl compounds, wherein the partially hydrolyzed vinyl ester resin has a degree of hydrolysis of at most 70 % by mole, it is contained in a concentration of at most 50 % by weight, and it satisfies the equation: ln y > 0.042x + 1.0, in which y is the cloud point ( DEG C) of a 30 % by weight aqueous solution of the partially hydrolyzed vinyl ester resin, and x is the degree of hydrolysis (% by mole) of the partially hydrolyzed vinyl ester resin. |
