IPC: C08G8/30

Abstract: Lacquers, varnishes, and coating compositions are prepared by incorporating a phenol-allyl resin with a cellulose derivative, with or without the addition of solvents, plasticizers, softeners, other resins, fire retardants, &c.  The resins are obtained by condensing a phenolic body, such as phenol, a cresol or xylenol, with allyl alcohol, its esters both organic and inorganic, e.g. the acetate, bromide or iodide, and its ethers, e.g. allyl ethyl ether and diallyl ether, preferably in the presence of a catalyst. 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, alcohol, benzene, ethylene dichloride, ethyl acetate, ethyl lactate, tetrachlorethane, and diacetone-alcohol.  As examples of plasticizers, reference is made to diphenylolpropane, triacetin, dibutyl tartrate, diethyl phthalate, and xylene monomethylsulphonamide.  Other resins mentioned are the artificial resins from phenol-formaldehyde and diphenylolpropane-formaldehyde, or the natural resins manila, acaroid, pontianak, kauri, dammar, rosin, shellac and ester gums. Brominated aromatic compounds, e.g. brominated tricresyl phosphate, may be present as fire retardants. Examples are given of the preparation of (1) coating compositions consisting of (a) cellulose acetate, cresol-allyl resin and acetone, (b) cellulose acetate, cresol-allyl resin, acetone, benzene, alcohol, and diacetone-alcohol, (c) cellulose nitrate, camphor, diethyl phthalate, cresol-allyl resin, benzene, alcohol, butyl alcohol, butyl and ethyl acetates; (2) a lacquer consisting of cellulose acetate, cresolallyl resin, diphenylolpropane, pigment, acetone, ethyl acetate and lactate, benzene and toluene.  In each case the cresol-allyl resin is prepared by condensing cresol with allyl alcohol or an allyl ester or ether.ALSO:Lacquers, varnishes, coating compositions, plastic materials, adhesives, filaments, and photographic and other films are prepared by incorporating a phenol-allyl resin with a cellulose derivative, with or without the addition of solvents, plasticizers, softeners, other resins, fire retardants, &c.  The resins are obtained by condensing a phenolic body, such as phenol, a cresol or xylenol, with allyl alcohol, its esters both organic and inorganic e.g. the acetate, bromide, or iodide and its ethers, e.g. allyl ethyl ether and diallyl ether, preferably in the presence of a catalyst.  Examples are given of the condensation of o-cresol with allyl alcohol and allyl iodide in the presence of zinc chloride, and of o-cresol with allyl acetate using ferric chloride as catalyst. 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, alcohol, benzene, ethylene dichloride, ethyl acetate, ethyl lactate, tetrachlorethane and diacetone-alcohol.  As examples of plasticizers, reference is made to diphenylolpropane, triacetin, dibutyl tartrate, diethyl phthalate and xylene monomethylsulphonamide.  Other resins mentioned are the artificial resins from phenol-formaldehyde and diphenylolpropane-formaldehyde, or the natural resins manila, acaroid, pontianak, kauri, dammar, rosin, shellac and ester gums. Brominated aromatic compounds, e.g. brominated tricresyl phosphate, may be present as fire-retardants.  Solutions containing a phenol-allyl resin and a cellulose derivative may be used as lacquers for coating metal, glass, &c., or for the production of filaments by wet or dry spinning methods.  Plastic materials containing a cellulose derivative and a phenol-allyl resin may be made into sheets of reinforcing material for reinforced glass, whilst a solution containing the resin may be used as an adhesive, especially for securing cellulose derivative sheets to sheets of glass in the manufacture of reinforced glass. Examples are given of the preparation of (1) coating compositions consisting of (a) cellulose acetate, cresol-allyl resin and acetone, (b) cellulose acetate, cresol-allyl resin, acetone, benzene, alcohol and diacetone-alcohol, (c) cellulose nitrate, camphor, diethyl phthalate, cresol-allyl resin, benzene, alcohol, butyl alcohol, butyl and ethyl acetates; (2) adhesives, specially suitable for securing sheets of material having a basis of a cellulose derivative to surfaces of glass, cardboard, asbestos, metal, comprising (a) cellulose acetate, cresol-allyl resin, acetone, ethyl acetate and lactate, (b) cellulose nitrate, camphor, dibutyl phthalate, cresol-allyl resin, benzene, alcohol, butyl alcohol and acetate, and ethyl acetate; (3) a plastic composition consisting of cellulose acetate, cresol-allyl resin, xylene monomethyl-sulphonamide, alcohol and benzene; (4) a solution for making filaments by dry spinning methods containing cellulose acetate, cresol-allyl resin and acetone; (5) a lacquer consisting of cellulose acetate, cresol-allyl resin, diphenylolpropane, pigment, acetone, ethyl acetate and lactate, benzene and toluene.  In each case the cresol-allyl resin is prepared by condensing cresol with allyl alcohol or an allyl ester or ether.ALSO:Plastic materials and adhesives are prepared by incorporating a phenol-allyl resin with a cellulose derivative, with or without the addition of solvents, plasticizers, softeners, other resins, fire retardants, &c.
