binder composition, process for the preparation of an aqueous binder composition, use of boric acid and / or at least one boric acid salt, use of a binder composition, surface coating material, adhesive, and cement.

摘要

An aqueous binder composition comprising: a) a water-insoluble polymer (P) in the form of dispersed polymer particles having a glass transition temperature in the range from 50° C. to 50° C., obtained by free-radical polymerization of ethylenically unsaturated monomers M, the monomers M comprising: 80% to 99.9% by weight, based on the total amount of monomers M, of at least one neutral, monoethylenically unsaturated monomer M1 of low water-solubility; and 0.1% to 20% by weight, based on the total amount of monomers M, of at least one monoethylenically unsaturated monomer M2 which carries at least one carboxyl group and/or at least one carboxamido group (CONH2); and b) boric acid and/or at least one salt of boric acid is provided. Also provided are a process to prepare the binder composition and the use thereof.
