| 摘要 |
This is a method for the preparation of polyurethane/acrylic-or-vinyl latexes for use in waterborne adhesives or coatings in which the urethane polymer component has no urea linkages. A fully reacted emulsifiable polyurethane is prepared in an acrylic or vinyl monomer, which acts as the solvent or diluent for the polyurethane. The monomer and polyurethane are then coemulsified, free radical initiators are added, and a regular acrylic or vinyl addition polymerization is carried out.
