Abstract
Thermally curable mixtures of hydroxyalkylated polyamines and polycarboxylic acids are formaldehyde-free and particularly useful as binders for shaped articles.
Claims22
An aqueous thermally curable composition comprising component
- (1) at least one water-soluble, linear or branched aliphatic compound containing at least two functional amino groups of the structure (a) or of the structure (b) ##STR21## where R is hydroxyalkyl and R' is alkyl, per molecule, component (2) an addition polymer containing from 5 to 100% by weight of units derived from at least one ethylenically unsaturated mono- or dicarboxylic acid obtained by free-radical polymerization and being essentially free of carboxylic anhydride structures, and
- (3) water.
