Abstract: Acid modified vinyl acetate interpolymers containing 2-acrylamido-2-methylpropanesulfonic acid and their use as textile sizes. The interpolymers comprise from about 64.5 to about 95.8 weight percent of vinyl acetate, from about 4 to about 9.5 weight percent of acrylic acid, from about 0.2 to about 1 weight percent of 2-acrylamido-2-methylpropanesulfonic acid and from about 0 to about 25 weight percent of an ethylenically unsaturated monomer selected from the group consisting of alkyl acrylates, dialkyl maleates, and dialkyl fumarates. The interpolymers are prepared preferably by latex polymerization. The textile size solutions are formed by dissolving the interpolymers in dilute aqueous bases or in an organic solvent, and can be used advantageously in combination with polyvinyl alcohol and starches. The sizes demonstrate excellent adhesion to spun polyester and spun blends of polyester and natural fibers and are readily removed by aqueous scouring solvents.

Abstract: Acrylic pressure-sensitive resins comprising at least one ester of acrylic acid or methacrylic acid containing from 6 to 20 carbon atoms and between 0.1 and 1.5 weight percent of 2-acrylamido-2-methylpropanesulfonic acid. The resins are prepared in aqueous emulsion and when coated on substrates and dried provide pressure-sensitive films with superior peel strength retention.
