Abstract

322,543. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). June 2, 1928. Divided on 322,466. Cements and adhesives comprise lower fatty acid esters of cellulose such as cellulose triacetate or butyrate, acetone-soluble cellulose acetate &c., and resinous condensation products of aromatic dibasic acids with hydroxy-alkyl ethers of trihydric alcohols. The resins may be obtained from phthalic or halogenated phthalic acids and the hydro-alkyl ethers of glycerol or its homologues such as penta-glycerol CH3. C- (CH2OH)2. The ethers may contain one to three hydroxyl-alkyl groups. The compositions may also comprise soluble or insoluble colouring materials; fillers such as lithopone, ground slate, graphite, kieselguhr etc.; solvents; small proportions of nitrocellulose; softeners; natural or artificial resins such as condensation products of urea and formaldehyde, and of aliphatic dibasic acids and polyhydric alcohols in less quantity than the essential resinous constituent. Solvents specified include lower glycol monoalkyl ethers and their lower fatty acid esters, such as acetates or formates, cyclic ketones, such as cyclohexanone, diacetone alcohol, methyl acetate, lower alcohols, lower aliphatic ketones such as acetone, diethyl ketone &c., dioxane or its homologues. ethyl, butyl, amyl or cyclohexyl acetates, liquid hydrocarbons, especially those of the benzene series, methylene chloride or mixtures of these materials. The Provisional Specification describes also resins from anv dibasic organic acids and hydroxy-alkyl ethers of polyhydric alcohols, as the resinous constituent of the compositions.
