Abstract
Epoxide resins are prepared by condensing a polyhydric phenol with a mono- or polynuclear benzene hydrocarbon having at least two chloromethyl groups in the molecule to give a linear condensate which is then condensed with a halohydrin, e.g. epichlorhydrin in presence of alkali. Chlormethyl compounds specified are xylylene dichlorides and their methyl derivatives and corresponding naphthalene compounds, while polyhydric phenols specified are hydroquinone, resorcinol p-p1-dioxydiphenyl-methane or -propane. The reaction may be carried out in presence of solvents, e.g. alcohols, ketones, ethers, esters and acid amides particularly butanol, benzyl alcohol, acetone cyclohexanone, dioxane and dimethylformamide. From 1-2 mols. of the chlormethyl compound are used per mol. phenol. In examples, (1) p,p1-dioxydiphenylpropane was stirred into a hot caustic soda solution and p-xylylenedichloride added. A resinous product was precipitated. NaOH was added and then epichlorhydrin. A light-brown resin was obtained. (2) as in (1), the reaction being carried out in benzyl alcohol using potassium carbonate as catalyst: (4) p-xylylenedichloride, bis-chlormethylnaphthalene and p,p1-dioxydiphenylpropane were dissolved in dimethylformamide, KOH being added and the mixture heated to 170 DEG C. After removal of inorganic salts the resin obtained was reacted with epichlorhydrin in aqueous alkali to yield an epoxy resin.
