Title: Methacrylic and acrylic esters of halogenated polyphenols and polymers derived therefrom
IPC: C08F20/16
Filed: 1962-09-19
Abstract: The invention relates to methacrylates or acrylates of nonachloromonohydroxydiphenyl or of octochlorodihydroxydiphenyl having the formula: <FORM:0955127/C2/1> where R1 is a hydrogen atom or a methyl group, R2 is the nonachlorodiphenyl radical and R3 is the octochlorodiphenyl radical.  The esters are produced by reacting a perchloro-mono- or diphenol derived from diphenyl, in the form of an isomer or a mixture of isomers of nonachloromonohydroxydipheny or octochlorodihydroxydiphenyl respectively, in an aqueous medium at reduced or moderate temperature with an alkaline salt of the diphenol and an acid chloride derived from methacrylic acid or acrylic acid to form the ester in the form of a precipitate, separating the precipitated ester from the solution, washing the ester in water until the washing water was clear of chloride ions, and drying the ester.  In an example methacrylyl chloride is dripped into a solution of the disodic salt of octochlorodihydroxydiphenyl at a temperature not exceeding 1 DEG C.  The ester, which is precipitated as a fine powder as it is formed, is collected on a filter, then washed with cold distilled water until the chloride ions had completely disappeared from the washing waters, and finally dried under reduced pressure at 50 DEG C. to give a product mainly composed of a mixture of mono- and di-methacrylate of octochlorodihydroxydiphenyl. Other examples describe the preparation of di-acrylate of octochlorodihydroxydiphenyl, methacrylate of nonachloromonohydroxydiphenyl, acrylate of nonachloromonohydroxydiphenyl.ALSO:A copolymer of a methacrylate or acrylate nonachloromonohydroxydiphenyl or of octochlorodihydroxydiphenyl having the formula: <FORM:0955127/C3/1> , or <FORM:0955127/C3/2> , or <FORM:0955127/C3/3> where R1 is a hydrogen atom or a methyl group, R2 is the nonachlorodiphenyl radical and R3 is the octochlorodiphenyl radical is obtained by the copolymerization with compounds such as styrene, methyl methacrylate, acrylonitrile, and unsaturated polyesters e.g. vinyl acetate.  One or more sulphuretted and/or oxygenated derivatives of phosphorus, antimony or bismuth may be added to the precursor of the polymer prior to polymerization. In an example the polymerization of methacrylate of nonachloromonohydroxydiphenyl was carried out in the absence of air with the aid of benzoyl peroxide. Other examples show the copolymerization of di-acrylate of octochlorodihydroxydiphenyl and methyl methacrylate, and the mixture of mono- and di-methacrylate of octochlorodihydroxydiphenyl with methyl methacrylate.
