| abstract | Oil soluble resinous materials are prepared by condensing formaldehyde with a chlorinated di- or trinuclear phenol having at least one but not more than two substitutable reactive positions, and at least three non-aromatic carbon atoms, one of which is directly joined to at least three carbon atoms and is directly joined to a benzene ring in one of the o- and p-positions to the phenolic hydroxyl group. Suitable phenols include di(4-hydroxy-3-chlorophenyl)dimethylmethane, di(4 - hydroxy - 3-chlorophenyl) - methylethylmethane, di(4-hydroxy - 3 - chlorophenyl) - propylmethane, di(2 - hydroxy - 5 - chlorophenyl) - dimethylmethane, and di(2-hydroxy-5-methyl-6-chlorophenyl)-phenylmethane. In an example di(4-hydroxy - 3 - chlorophenyl)diphenylmethane is condensed with formaldehyde in the presence of caustic soda and the product is blended with chinawood oil and thinned with mineral thinner and aromatic hydrocarbons to yield a varnish. The products may be blended with cellulose derivatives such as nitrocellulose, cellulose acetate, benzyl cellulose and ethyl cellulose; natural resins and ester gums such as rosin, kauri, copal, and rosin glyceride; synthetic resins or synthetic resin forming material such as metastyrene, coumarone - indene resins, amine-aldehyde resins, acrylic ester resins, vinyl resins, casein plastics, polyhydric alcohol-polybasic acid condensation products not modified with drying oils or drying oil acids; bitumens such as asphalts; waxes such as beeswax, candelilla wax, montan wax, carnauba wax and lauryl stearate; other ester-like bodies such as stearin, castor oil, hydrogenated castor oil, tricresyl phosphate, dibutyl phthalate, triethylin, animal fats and waxes; pigments; solvents; plasticizers; antioxidants; fillers and lakes for use in the manufacture of coating compositions, moulding plastics, impregnating agents for paper, wood, cloth, stone or rubberized fabrics, adhesives for safety glass, linoleum, adhesives, cements, sealing waxes, insulating materials together with mica or asbestos and laminated sheet or tubes from cellulose derivatives such as cellulose acetate. Specification 435,762 is referred to. Di(4 - hydroxy-3-chlorophenyl)dimethylmethane is obtained by chlorinating the parent body in solution in carbon tetrachloride by means of a solution of chlorine in carbon tetrachloride. |
