    Abstract: 1. Carboxyl-containing vinyl chloride copolymers containing copolymerized units of vinyl chloride, diesters of alpha,beta-olefinically unsaturated dicarboxylic acids with monoalkanols and alpha,beta-olefinically unsaturated carboxylic acids or dicarboxylic acid monoesters, the copolymers containing a) 65 to 85 % by weight of copolymerized units of vinyl chloride, b) 15 to 35 % by weight of copolymerized units of at least one diester of an alpha,beta-olefinically unsaturated dicarboxylic acid with monoalkanols of 1 to 10 carbon atoms, and c) 0.3 to 10 % by weight of copolymerized units of at least one copolymerizable alpha,beta-olefinically unsaturated carboxylic acid or of at least one monoester of an alpha,beta-olefinically unsaturated dicarboxylic acid with monoalkanols of 1 to 18 carbon atoms with the proviso that the sum of the percentages given in a), b) and c) is 100, and the copolymers having acid numbers of from 3 to 30 and K values of from 40 to 60, characterized in that the copolymers have been obtained by emulsion polymerization in the presence of nonionic emulsifiers and subsequent conventional working up by precipitation and drying.
