20120270992 | SURFACTANT-FREE CORE-SHELL HYBRID LATEXES - The invention provides core-shell hybrid latexes wherein the core comprises poly(acrylate)polymers and the shell comprises vegetable oil-based waterborne polyurethanes, and the latexes lack surfactants. Surfactant-free core-shell hybrid latexes with waterborne vegetable oil-based polyurethanes as the shell and poly(acrylate) as the core have been successfully prepared by seeded emulsion polymerization. The crosslink densities of the polymers obtained can be controlled by using modified vegetable oil polyols with various hydroxyl numbers or by adding a multifunctional vinyl crosslinker to the poly(acrylate) core. | 10-25-2012 |
