Abstract: A sprayable granite-like coating composition useful for forming simulated stone surfaces, such as polished granite, such surfaces having high-impact strength, superior hardness and an aesthetically pleasing look. The coating composition comprises gel resin matrix based on unsaturated crosslinkable polyester or acrylic resins, a curing accelerator composition and granules comprising thermoset resins or mixtures of thermoplastic and thermoset resins. The gel coat resins and the granules are visually differentiable, substantially immiscible and substantially equal in density. The composition, is characterized by forming coatings of uniform thickness and quick curing that even at low thickness provides a uniform granite appearance.

Abstract: The present invention relates to novel condensation polymers where N,N*-disubstituted disulfonamides are copolymerized with an organic acid dihalide such as dicarboxylic acid dichlorides, disulfonic acid dichlorides, bis chloroformates, diphosphoryl acid dichlorides, diphosphonyl acid dichlorides, or phosgene or with diisocyanates. The polymers obtained are thermoplastic and useful in molding and extrusion application.
