Abstract
Heat-curable aqueous compositions which comprise a carboxyl-containing polymer component and optionally a hydroxyalkylated amine are used as binders for shaped articles.
Claims22
A heat-curable aqueous composition, comprising at least one polymer (A1), which contains from 0 to 5% by weight of an α,β-ethylenically unsaturated mono- or dicarboxylic acid in copolymerized form and which is obtained by free-radical polymerization in the presence of
- (a) at least one polymer (A2) obtained by free-radical polymerization and containing from 15 to 100% by weight of an α,β-ethylenically unsaturated mono- or dicarboxylic acid in copolymerized form, and
- (b) at least one amine comprising at least one long chain having at least six carbons, wherein the weight ratio (based on solids) of polymer (A1) to polymer (A2) is from 7:1 to 1:7 and that of polymer (A2) to long-chain amine is from 20:1 to 2:1.
