Polycationic latex wet strength agent

摘要

Polycationic wet-strength materials such as KYMENE are chemically modified to provide unsaturated hydrocarbon substituents. The modified KYMENE is cross-linked onto and into latex particles to provide improved wet-strength agents for use in paper treatments. Thus, KYMENE is reacted, for example, with acrylic acid and cross-linked with styrene/butadiene to provide a polycationic latex wet-strength agent.
