Abstract

PURPOSE: To obtain the titled flexible polymer having a flexible matter surface with few fish-eyes, by copolymerizing vinyl chloride monomer with a specific comonomer in the presence of a specific partially sponified PVA as a dispersing agent.
CONSTITUTION: (A) A polymerizable monovinyl compound containing vinyl chloride as a principal component is subjected to the suspension polymerization with (B) a polyalkylene glycol di(meth)acrylate, e.g. polyethylene glycol diacrylate, in an aqueous medium containing (C) PVA with a saponification degree of 65W 78mol%, having a viscosity of 4W15cp at 20°C in a 4% aqueous solution thereof and 0.03mol% or more carbonyl groups as a dispersing agent in the presence of (D) an oil-soluble polymerization initiator, e.g. lauroyl peroxide, to give the aimed copolymer. Preferably, the amount of the component (B) is 0.1W2wt% based on the component (A), and the amount of the dispersing agent (C) is 0.06W0.3wt%, based on the component (A).
