ABSTRACT:
An effective amount of a vinylbenzyltrialkylammonium salt, prepared from a vinylbenzyl halide and a tertiary amine, is polymerized with various other monomers to afford stable latex polymers which have the latex stabilizing surfactant incorporated into the polymer backbone. The use of a vinylbenzyltrialkylammonium salt lessens or avoids the usual problems associated with the conventional anionic, nonionic or cationic emulsifiers employed in aqueous polymerizations; that is, the latex stabilizing surfactant incorporated into the polymer backbone is the sole emulsifier employed. The copolymers prepared with the quaternary ammonium compounds are useful as sizing agents, as extender/binders for cationic water repellents; in addition, the polymers are depositable on pulp without requiring any deposition aids or defoamers.
