Abstract 540,168. Synthetic resinous compositions. AMERICAN CYANAMID CO. Dec. 28,1939, No. 33000. Convention date, Dec. 30, 1938. [Class 2 (iii)] Substantially insoluble, substantially infusible resins are prepared by polymerizing, by heat and/or light in the presence of a catalyst, a mixture comprising a resin obtained by the esterification of an α, #, unsaturated organic acid with a polyhydric alcohol, and an organic substance containing at least one polymerizable reactive allyl group, and which preferably has a high boiling point. Polymerization inhibitors and drying oil acids may be present in the mixture. The resins may be compounded with fillers such as wood flour, wood fibre, paper dust, clay, zein, glass wool, mica, granite dust, silk flock, cotton flock, steel wool, carborundum, cloth and sand, with dyes, pigments, natural resins, other synthetic resins, rubber and cellulose derivatives, and the resulting compositions may be used as coating compositions, as adhesives, and for moulding. Specified α, #, unsaturated organic acids are maleic, fumaric, itaconic, citraconic, mesaconic, aconitic, and halogenated maleic acids, and these may be substituted in part with acrylic, #-benzoyl acrylic, methacrylic, #<SP>1</SP>-cyclohexene carboxylic, cinnamic and crotonic acids. Specified polyhydric alcohols are glycols, glycerol and pentaerythritol. Specified reactive allyl compounds are diallyl maleate, fumarate, phthalate and succinate, allyl alcohol, 2-chlorallyl alcohol, methallyl alcohol, triallyl tricarballylate, triallyl phosphate, allyl cellulose, methallyl cellulose and crotyl cellulose. Specified polymerization catalysts are benzoyl, phthalic, succinic, benzoyl acetic, cocoanut oil acid, stearic and oleic peroxides, tertiary butyl peroxide, ascaridole, cobalt linoleate and naphthenate, p-toluene sulphonic acid, aluminium chloride, stannic chloride and boron trifluoride. Specified polymerization inhibitors are hydroquinone, benzaldehyde, 1-ascorbic acid, resorcinol, tannin, sym x, #-naphthyl p-phenylene diamine, and phenolic resins. Examples are given, describing the preparation of resins from mixtures of :- (1) diethylene glycol maleate resin with diallyl maleate, fumarate, phthalate or succinate: (2) ethylene glycol maleate resin with diallyl succinate, methyallyl alcohol, diallyl phthalate or diallyl maleate : (3) decamethylene glycol maleate resin with diallyl sebacate : (4) α- propylene glycol maleate resin with a resin prepared from ethylene glycol, phthalic anhydride and allyl alcohol: (5) ethylene glycol maleate resin, triethylene glycol phthalicfumaric acid resin and diallyl maleate : (6) a resin prepared from phthalic anhydride, triethylene glycol, linseed oil, maleic anhydride and ethylene glycol, with diallyl maleate : (7) a resin prepared from glycerol, maleic anhydride, linseed oil acids and undecylenic acid, with diallyl maleate : (8) a resin prepared from diethylene glycol, maleic anhydride, phthalic anhydride, linseed oil acids and glycerol, with diallyl maleate : (9) a resin prepared from maleic anhydride, sebacic acid, ethylene glycol and linseed oil fatty acids, with diallyl maleate. Examples are also given of the preparation of the starting resin, which is to be polymerized with the allyl compound, from maleic anhydride and ethylene glycol, diethylene glycol, or α- propylene glycol. Specifications 497,175 and 540,167 are referred to.
