Title: Coating compositions

Abstract: A synthetic resin is prepared by the polymerization of a divinyl benzene C6H4 (CH : CH2)2 by methods similar to those used with styrene, e.g. at room temperature, either alone or in the presence of stannic chloride, or by heating in the presence of benzoyl peroxide. A soluble product is obtained by polymerizing in the presence of a solvent, e.g. xylene, toluene, or benzene, and the solvent may be removed, or the product may be precipitated by pouring into a non-solvent liquid.  Flexible durable films are formed from the resin in admixture with a drying oil, e.g. raw linseed or tung oil, and the resin may be used with a drying oil in lacquers, enamels, varnishes, paints, and plastic compositions.  In examples, (1) divinyl benzene is heated with xylene and a little benzoyl peroxide under a reflux for four hours and the solution poured into alcohol to precipitate the resin; (2) toluene is used in place of xylene and is removed by steam distillation; the distillate contains some divinyl benzene and is treated with a further quantity of benzoyl peroxide; (3) divinyl benzene is dissolved in benzene, a little stannic chloride is added, and the mixture allowed to stand for twelve hours and then poured into alcohol; (4) a clear lacquer consists of the resin, raw linseed oil, cobalt oleate, toluene, and xylene; (5) a white enamel consists of the same ingredients and zinc oxide.ALSO:A synthetic resin is prepared by the polymerization of a divinylbenzene C6H4 (CH : CH2)2 by methods similar to those used with styrene, e.g. at room temperature, either alone or in the presence of stannic chloride, or by heating in the presence of benzoyl peroxide.
