Abstract: The invention provides finely divided vulcanized rubber having a particle size of generally less than 20 microns for re-use in the rubber industry. Vulcanizates produced from compositions containing the finely divided vulcanized rubber, either as the sole rubber component or in admixture with unvulcanized rubber, have properties significantly better than those of vulcanizates of similar compositions containing conventional reclaimed rubbers. Vulcanized rubber is converted into the finely divided rubber by the steps of (1) contacting vulcanized rubber with a fatty acid, (2) contacting the product of step (1) with a solid alkali and (3) forming a dispersion of the product of step (2) with a liquid which dissolves the alkali but does not affect the rubber. Alternatively, the finely divided vulcanized rubber results from the steps of (1) contacting the vulcanized rubber with a liquid effective to swell the rubber and thereby weaken it e.g.

Abstract: Unsaturated polyester resin systems are modified to provide a curable, stable water-in-oil emulsion by reacting the resin system with a hydrolized source of hypochlorite ion, while maintaining during the reaction a pH of at least 4, whereby the reaction is predominantly one of chlorohydration. The hypochlorite ion may be provided by addition of an aqueous solution of an inorganic salt of hypochlorous acid, e.g. by an aqueous solution of sodium, potassium, lithium, or calcium hypochlorite; or by an aqueous solution of a suitable chloramine; or the additive may comprise the reaction product of a chloramine with an aqueous solution of an inorganic salt of hypochlorous acid. The modified resin system yielded by the invention may include over 50% by weight of water; and high quantities of conventional fillers may be added without disrupting the emulsion.
