A method for the production of carboxylate, copolymers of monoethylenically unsaturated mono - and dicarboxylic acids as well as carboxylate rich copolymers having a low degree of neutralization

摘要

Production of carboxylate, copolymers of monoethylenically unsaturated mono - and dicarboxylic acids having an average molecular weight m_w of at least 3000 g / mol, as well as at least 20,1 w -% of the dicarboxylic acid by free radical polymerization in the presence of 2 to 19,9 molar equivalents of an organic amine, based on the total amount of all the cooh - groups of the mono - and dicarboxylic acids, in the case of a temperature of not more than 130°C. carboxylate rich copolymers having a low degree of neutralization, which are obtainable by the method, and use of such copolymers for the treatment of surfaces and as binders for fiber bonding.
