Vinyl acetate/ethylene paint latices stabilized with urethane linked poly(ethylene glycols) and polyoxyethylene-polyoxyalkylene glycols |
摘要 |
This invention relates to improved vinyl acetate/ethylene copolymers emulsions polymerized in the presence of colloidal, nonionic, water dispersible polyurethanes. The improvement resides in polymerizing the vinyl acetate and ethylene in the presence of a costabilizer comprised of the colloidal, nonionic, water dispersible polyurethanes and a polyoxyethylene-polyalkylene glycol, a particularly polyoxyethylene-polyoxypropylene glycols.
