| titleOfInvention | Chalk-resistant, medium to dark colored polyurethanes, polymer/polyol and polyisocyanate compositions for use in producing same and methods for making said polyurethanes |
| abstract | ABSTRACT OF THE DISCLOSURE Improvements in polymer/polyol compositions which are convertible by reaction with polyisocyanates to poly-urethanes which are pigmented to a medium to dark color and which inherently chalk upon exposure to weather and wherein the polymer of the polymer/polyol composition is dispersed in the polyol thereof and is formed from one or more poly-merizable ethylenically unsaturated monomers. The improve-ment provides to said polyurethanes resistance to chalking on exposure to weather and in one embodiment comprises the presence, in the polymer/polylol compositions used to make the polyurethanes, of a metallocene from the class consisting of ferrocene, ferrocene derivatives, cobaltocene and nickel-ocene in an amount effective to provide chalk resistance. Optionally, the metallocene can be present in the polyiso-cyanate composition instead of the polymer/polyol composition. Improved dark colored polyurethanes are made by reacting a mixture comprising (a) a polymer/polyol composition and (b) an organic polyisocyanate in the presence of (c) a catalyst for the reaction of (a) and (b), (d) a metallocene, preferably ferrocene, or a ferrocene polymer and (a) a medium to dark pigment to produce the polyurethane. |
