| 摘要 |
Aqueous dispersions of vinyl polymers are disclosed. The polymers are copolymers of a vinyl halide, a vinyl ester, e.g., vinyl acetate, and a poly(alkylene glycol)-based macromonomer, e.g., poly(ethylene glycol) - maleic anhydride. Also disclosed are processes for the preparation of the aqueous dispersions which comprise forming the copolymer by solution polymerization, converting the dissolved polymer into an aqueous dispersion and removing the solvent from the aqueous dispersion. |
