  • Acid-modified poly(vinyl acetate) textile sizes
    Patent number: 4013805
    Abstract: Acid-modified poly(vinyl acetate) textile sizes and textiles sized therewith. The sizes comprise interpolymers of 90.5 to 95.5 percent by weight vinyl acetate, 4.0 to 7.5 percent by weight acrylic acid and 0.5 to 2.0 percent by weight of a monoalkyl ester of maleic, fumaric, or citraconic acids. The interpolymers are prepared preferably by latex interpolymerization. They are used for sizing spun polyester and spun blends of polyester and natural fibers.

  • Articles coated with pressure-sensitive interpolymers containing 2-acrylamido-2-methylpropanesulfonic acid
    Patent number: 4012560
    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.
