Abstract
Surfactant mediated, free radical initiated emulsion/dispersion polymerization of n-vinylformamide with styrene or substituted styrene copolymers, and its subsequently hydrolyzed products bearing formamide, amine and styrenic functionality are disclosed. Processes for polymerization, polymer composition, and hydrolysis of such polymers are also disclosed. These polymers bearing cationic functionality can be used in papermaking applications as dry strength additives, wet strength additives, retention aids, drainage aids, sizing agent, sizing promoter and pitch and stickies control agents.
