Abstract
Synthetic resins are prepared by condensing an aryloxyphosphoryl dichloride with a dihydric phenol, the hydroxyl groups of which are attached to non-adjacent carbon atoms. Catalysts, e.g. tin, calcium chloride, boron trifluoride, or zinc or aluminium chloride may be present, or the reaction may be performed in a solvent, e.g. ether, benzene or chloroform with, if desired, an acid acceptor, e.g. a tertiary amine such as pyridine, present. Specified phenols are hydroquinone, resorcinol, chlorinated hydroquinone, dihydroxy naphthalene, 2,21- or 4,41-dihydroxydiphenyl and chlorinated dihydroxydiphenyl. Specified aryloxyphosphoryl dichlorides are phenoxyphosphoryl dichloride; p - chlorophenoxyphosphoryl dichloride; o - chlorophenoxyphosphory dichloride; 2,4-dichlorophenoxyphosphoryl dichloride; 2,4,6-trichlorophenoxyphosphoryl dichloride; 2,4-dibromophenoxyphosphoryl dichloride; o-methylphenoxyphosphoryl dichloride; 2-methyl-4,6-dichlorophenoxyphosphoryl dichloride. They may be prepared by the method of Specification 644,467, [Group IV (b)]. Reaction may be effected by heating progressively from 100-180 DEG C. to 190-240 DEG C. Preferably the mixture is stirred. An inert atmosphere may be maintained. The products are soluble in dioxane, chloroform, benzene-alcohol mixtures, benzene, toluene, or mixtures of butyl or amyl acetate and aromatic hydrocarbons containing minor proportions of aliphatic alcohols. Some of these are soluble in butyl acetate, ethyl acetate, and acetone. They may be purified by dissolving them in benzene and precipitating with ether and by washing with sodium carbonate. They may be rendered infusible by heating with metallic oxides, e.g. litharge. They are compatible with nitrocellulose, ethyl cellulose and polyvinyl chloride. A number of examples are given of the preparation of resins according to the invention.
