Abstract

322,539. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). June 2, 1928. Divided on 322,466. Compositions containing cellulose derivatives. -Filling compositions comprise nitro-cellulose and resinous condensation products of aromatic dibasic acids with hydroxy-alkyl ethers of glycerols with glycols or glycerols. The resins may be obtained from phthalic or halogenated phthalic acids and the said hydroxy-alkyl ethers of glycerol or its homologues such as pentaglycerol CH3 C(CH2OH)2. The ethers may contain one to three hydroxy-alkyl groups either of a glycol or a glycerol. The compositions may also comprise soluble or insoluble colouring materials; fillers such as lithopone, ground slate, graphite, kieselguhr etc.; solvents; small proportions of cellulose aliphatic carboxylates such as cellulose acetate; softeners; natural or artificial resins such as condensation products of cyclic ketones, of urea and formaldehyde and of dibasic acids and polyhydric alcohols in a quantity not more than that of 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. Examples are given. The Provisional Specification also describes compositions comprising nitro-cellulose and resins from organic dibasic acids and hydroxy alkyl ethers of glycerol or glycol.
