ABSTRACT:
Polycationic wet strength agents such as KYMENE are chemically modified and cross-linked into and onto the surface of latex particles. Paper treated with the resulting polycationic latex particles exhibits enhanced wet strength. Thus, KYMENE is reacted, for example, with acrylic acid and cross-linked with styrene/butadiene to provide a polycationic latex which is used to treat paper. Paper sheets, bags, containers and the like are provided. Also provided are paper towels, and the like, having super-absorbent materials incorporated therein.
