Title: Improvements in or relating to compositions of matter having a basis of a cellulose derivative
IPC: C08K5/13
Filed: 1929-11-26
Abstract: Lacquers, varnishes, and coating compositions are prepared by incorporating a diphenylol-cycloparaffin with a cellulose derivative, with or without the addition of solvents, other plasticizers, softeners, resins, &c.  The diphenylol-cycloparaffins are crystalline compounds of definite chemical composition which may be prepared by condensing cyclic ketones, such as cyclohexanone, cyclopentanone, cycloheptanone and their alkyl or aryl derivatives, with phenolic compounds, such as phenol, cresol and halogenated phenols, in the presence of an acid condensing agent.  The cellulose derivative may comprise the nitrate, acetate, formate, propionate, butyrate or other ester, or ethyl-cellulose, methyl-cellulose, benzyl-cellulose or other ether.  Of the solvents which may be used are mentioned acetone, ethyl alcohol, methyl alcohol, benzene, chloroform, ethyl lactate, butyl alcohol, butyl acetate and diacetone-alcohol.  As examples of other plasticizers, reference is made to diethyl phthalate, dibutyl phthalate, triacetin, diphenylol-propane and diethyl tartrate.  Resins mentioned are the artificial resins from phenolaldehyde, diphenylolpropane - formaldehyde, diphenylolpropane-acetone, and lactic acid condensation, or the natural resins dammar, rosin, kauri, accaroides and ester gums. Examples are given of the preparation of (1) a coating composition consisting of cellulose acetate, diphenylol-cyclohexane and acetone, to which benzyl alcohol, ethyl lactate or diacetone-alcohol may be added; (2) a coloured coating composition comprising cellulose acetate, diphenylol-cyclohexane, a pigment, acetone, benzene, alcohol and ethyl butyrate; (3) a composition containing cellulose acetate, a natural or artificial resin, diphenylol-cyclohexane, acetone, ethyl acetate and diacetone-alcohol; (4) a composition containing cellulose nitrate, diphenylol-cyclohexane, ester gum, benzene, ethyl and butyl alcohols, and ethyl and butyl acetates; (5) a solution containing benzyl-cellulose, diphenylol-cyclohexane, toluene, ethyl acetate and ethyl lactate.ALSO:Lacquers, varnishes, coating compositions, plastic materials, moulded articles, filaments, photographic and other films, and adhesives are prepared by incorporating a diphenylol-cycloparaffin with a cellulose derivative, with or without the addition of solvents, other plasticizers, softeners, resins, &c. The diphenylol-cycloparaffins are crystalline compounds of definite chemical composition which may be prepared by condensing cyclic ketones, such as cyclohexanone, cyclopentanone, cycloheptanone and their alkyl or aryl derivatives, with phenolic compounds, such as phenol, cresol and halogenated phenols, in the presence of an acid condensing agent.  An example is given of the preparation of diphenylol-cyclohexane by heating cyclohexanone (1 mol.) with phenol (2 mols.) for 24 hours under a reflux at 70-80 DEG  C. in the presence of hydrochloric acid solution, and crystallizing out the product.  The cellulose derivative may comprise the nitrate, acetate, formate, propionate, butyrate or other ester, or ethyl-cellulose, methyl-cellulose, benzyl-cellulose or other ether.  Of the solvents which may be used are mentioned acetone, ethyl alcohol, methyl alcohol, benzene, chloroform, ethyl lactate, butyl alcohol, butyl acetate and diacetone-alcohol.  As examples of other plasticizers, reference is made to diethyl phthalate, dibutyl phthalate, triacetin, diphenylolpropane and diethyl tartrate.  Resins mentioned are the artificial resins from p  phenolaldehyde, diphenylolpropane - formaldehyde, diphenylolpropane-acetone, and lactic acid condensation, or the natural resins dammar, rosin, kauri, accaroides and ester gums. Examples are given of the preparation of (1) a coating composition consisting of cellulose acetate, diphenylol-cyclohexane and acetone, to which benzyl alcohol, ethyl lactate or diacetone-alcohol may be added; (2) a coloured coating composition comprising cellulose acetate, diphenylol-cyclohexane, a pigment, acetone, benzene, alcohol and ethyl butyrate; (3) a composition containing cellulose acetate, a natural or artificial resin, diphenylol-cyclohexane, acetone, ethyl acetate and diacetone-alcohol; (4) a composition containing cellulose nitrate, diphenylol-cyclohexane, ester gum, benzene, ethyl and butyl alcohols, and ethyl and butyl acetates; (5) a solution containing benzyl-cellulose, diphenylolcyclohexane, toluene, ethyl acetate and ethyl lactate; (6) a plastic composition comprising cellulose acetate, diphenylol-cyclohexane, alcohol and benzene; (7) a composition, suitable for spinning to form artificial silk, bristles, &c. consisting of cellulose acetate, diphenylol-cyclohexane and acetone; (8) an adhesive, specially useful for the manufacture of splinterless glass from sheets of glass and sheets having a basis of a cellulose derivative, comprising cellulose acetate, diphenylolcyclohexane, a light-coloured resin, acetone, ethyl lactate, benzene and alcohol. In each of the examples the proportions of the constituents are given.ALSO:Coating compositions, plastic materials, moulded articles and adhesives are prepared by incorporating a diphenylol-cycloparaffin with a cellulose derivative, with or without the addition of solvents, other plasticizers, softeners, resins, &c.
