Abstract

Aqueous dispersions of copolymers of (1) acrylic or methacrylic acid esters, (2) derivatives of acrylic acid or methacrylic acid having the general formula ##STR1## wherein Y is oxygen or a --NR"-- group where R" is hydrogen or alkyl having 1-4 carbon atoms, R is hydrogen or methyl, R' is hydrogen or alkyl having 1-4 carbon atoms, and n is an integer from 1 to 25, (3) one or more polymerizable carboxylic acids and/or the salts thereof, and (4) one or more monomers capable of crosslinking the polymer chains. These copolymers are highly water absorbent, and alkali-resistant, and applied as dispersions are well suited for providing a hydrophilic finish to textile fibers and to textiles and non-wovens.
