    Abstract: Textiles are stiffened by treating with compositions comprising (1) aqueous solutions of copolymers (see Group IV(a)) of 10 to 95% methacrylamide, 5% to 45% of an ethylenically unsaturated carboxylic acid ester or an ethylenically unsaturated nitrogen-containing basic compound and 0 to 85% of one or more other ethylenically unsaturated carboxylic acid amides, said copolymers having a K value of 20 to 120, and (2) aqueous alumina gel or zirconium oxide gel. The compositions may also comprise paraffin or other waxes and the finish may be rendered fast to boiling by adding condensates containing methylol groups derived from formaldehyde or glyoxal, e.g. with urea, melamine or dicyandiamide, and heating in the presence of a hardening agent. Examples describe compositions comprising copolymers of (1 and 2) methacrylamide and methyl acrylate ; (3) methacryl-amide and ethyl acrylate ; and methacrylamide with (a) methyl acrylate, (b) acrylamide and methyl acrylate, (c) vinyl imidazole, (d) methyl acrylate and vinylimidazole, and (e) diethylaminoethyl acrylate.

    Abstract: An aqueous emulsion contains liquid or solid paraffin, a wax, an oil, a fat, or a resin; a salt of a di-, tri- or tetra-valent weakly basic metal, such as zirconyl acetate, and 2 to 20% of an alcohol containing not more than 5 carbon atoms in the molecule. The alcohol may be primary, secondary, or tertiary and may have a branched chain but should not saturate the aqueous phase. The emulsions may contain fatty or montanic acids.
