Abstract

PURPOSE: To prepare the titled polymer having a viscosity of a specific range and useful as an emulsifier for the polymerization of (meth)acrylic acid ester, by copolymerizing an N-sulfoalkyl (meth)acrylamide with a vinyl ester in an alcohol solvent, and saponifying the copolymer.
CONSTITUTION: An N-sulfoalkyl (meth)acrylamide of formula I (R2 is H or methyl; R2 is alkylene; M is H or alkali metal) is copolymerized with a vinyl ester (e.g. vinyl acetate) in ≤50wt%, based on the vinyl ester, of an alcohol as a solvent. The copolymer is partially hydrolyzed to obtain the objective polymer having a viscosity of ≥5cps (as 4% aqueous solution at 20°C) and composed of the unit of formla II, the vinyl ester unit for formula III (R3 is alkyl) and PVA unit of formula IV.
