ABSTRACT:
Disclosed herein is a composition and method for sizing textiles which employs as the sizing agent a mixed salt comprising the reaction product of an interpolymer with a fixed alkali base and a fugitive alkali base; the latter subsequently being volatilized away during processing of the sized textile. The interpolymer comprises (a) 1.0 molar proportion of a maleic or fumaric acid or anhydride or partial ester, (b) from 0.1 to 3.0 molar proportion of a monovinylidene aromatic monomer and (c) from zero to a finite molar proportion of an alpha-olefin, a vinyl ester alpha-beta-ethylenically unsaturated nitrile, an acrylic or methacrylic ester or a vinyl alkyl ether. From 10 to 70% of the free carboxyl groups of the interpolymer are combined with fixed base, i.e., non-volatile amine or alkali metal base, and from 5 to 90% of said free carboxyl groups are combined with fugitive base, i.e., ammonia, ammonium hydroxide or volatile amine.
