ABSTRACT:
The new film forming polymeric material is useful in coating, binder, adhesive, and thickening applications. It comprises the addition free-radical polymerization product formed by polymerizing a monomeric mixture consisting essentially of, by weight percent: 1 to 20% of 1,1 dimethyl-1,(2-hydroxypropyl) amine methacrylimide; 8 to 45% of N-vinyl pyrrolidone; and 35 to 89% of vinyl acetate. Solvent polymerization in acid media is preferred. Polymerization in the presence of a small amount of cross-linking agent (such as allyl diglycol carbonate) improves the resistance of the resulting product to softening under high humidity conditions, preferably without destroying its solubility in ethanol.
