Polymers prepared in the presence of colloidal polyurethane dispersions |
| 摘要 |
Disclosed are improved vinyl acetate/ethylene copolymers emulsion polymerized in the presence of colloidal, nonionic, water dispersible polyurethanes. The improvement resides in vinyl acetate and ethylene polymerized in the presence of a costabilizer comprising the colloidal, nonionic, water dispersible polyurethanes and polyvinyl alcohol.
