HIGH SOLIDS ETHYLENE-VINYL ACETATE LATEX |
| 摘要 |
The present invention is directed to an ethylene-vinyl acetate dispersion and a process for making the dispersion by polymerizing a monomer mixture having vinyl acetate and ethylene in a batch process, in the presence of a stabilizing system of polyvinyl alcohol and without added surfactants, to form an ethylene-vinyl acetate polymer dispersion. The copolymer dispersion has a solids level of greater than 65 percent by weight, and a viscosity of less than 5000 mPa.s when measured at 65 percent solids at 25° C. The dispersion can be dried to form a redispersible powder. Both the dispersion and powder are useful in adhesive and coating formulations. |
