Water-dispersible polyurethane-vinyl polymer compositions |
| 摘要 |
A polyurethane dispersion is prepared by reacting a hydroxy-functional sulfonated unsaturated alkyd with an isocyanate in the presence of one or more vinyl monomers to form a blend containing the vinyl monomers and a sulfonated polyurethane polymer containing ethylenic groups. The blend is dispersed in water and the vinyl monomers are reacted by free radical polymerization.
