Compatible and reactive vinyl copolymer resn
Abstract
Abstract A terpolymer of vinyl chloride, vinyl acetate and an acrylic ester having the formula: WHEREIN R'', R2 and R3 may be hydrogen and methyl, in which the vinyl chloride mer content is about 50 to about 69 weight percent, based on the terpolymer weight, the acrylic ester mer content is about 2 weight percent to about 18 weight percent, based on the terpolymer weight, and the vinyl acetate mer content is at least 25 weight percent, based on the terpolymer weight, and said terpolymer has an inherent viscosity of about 0.15 to about 0.5, determined at 30* C using 0.2 grams of the terpolymer in a deciliter of cyclohexanone. These terpolymer resins can be employed alone or in admixture with other resins (such as nitrocellulose and polyurethanes) to make useful coatings.
