Title: Compositions of matter containing cellulose derivatives and products obtained therefrom
IPC: C08L1/12
Filed: 1930-11-07
Abstract: Lacquers, varnishes and coating compositions, are prepared by incorporating a phenol-chlorketone 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, cresol, xylenol and diphenylolpropane, with a chlorketone, such as monochlormethylethylketone and monochloracetone, preferably in the presence of an acid catalyst.  The cellulose derivative may comprise the nitrate, acetate, formate, propionate, butyrate or other ester, or ethyl-cellulose, methylcellulose, benzyl-cellulose or other ether. Of the solvents which may be used are mentioned acetone, alcohol, benzene, ethylene dichloride, ethyl acetate, ethyl lactate, tetrachlorethane, benzyl alcohol 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, acaroides, pontianak, kauri, dammar, rosin, shellac and ester gums.  Brominated organic 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, resin and acetone, (b) cellulose acetate, resin, acetone, benzene, alcohol and diacetone-alcohol, (c) cellulose nitrate, camphor, diethyl phthalate, resin, benzene, alcohol, butyl alcohol, butyl acetate and ethyl acetate ; (2) a lacquer consisting of cellulose acetate, resin, diphenylolpropane, pigment, acetone, ethyl acetate, benzene, toluene and ethyl lactate. In both Examples the resin employed is a phenolchlorketone resin and the proportions of the constituents are given.ALSO:Lacquers, varnishes, coating compositions, plastic materials, adhesives, filaments, photographic and other films are prepared by incorporating a phenol-chlorketone 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, cresol, xylenol and diphenylolpropane, with a chlorketone, such as monochlormethylethylketone and monochloracetone, preferably in the presence of an acid catalyst. Examples are given of the condensation of phenol, o-cresol, m-cresol and diphenylolpropane with chloracetone in the presence of concentrated hydrochloric acid.  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, benzyl alcohol 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, accroides, pontianak, kauri, dammar, rosin, shellac and ester gums.  Brominated organic compounds, e.g. brominated tricresyl phosphate, may be present as fire retardants. Solutions containing a phenol-chlorketone resin and a cellulose derivative may be used as lacquers for coating metal, glass, etc.; or for the production of filaments by wet or dry spinning methods; or for securing cellulose derivative sheets to sheets of glass in the manufacture of reinforced glass.  Plastic materials containing a cellulose derivative and a phenol-chlorketone resin may also be made into sheets of reinforcing material for reinforced glass. Examples are given of the preparation of (1) coating compositions consisting of (a) cellulose acetate, resin and acetone, (b) cellulose acetate, resin, acetone, benzene, alcohol, and diacetone-alcohol, (c) cellulose nitrate, camphor, diethyl phthalate, resin, benzene, alcohol, butyl alcohol, butyl acetate, and ethyl acetate; (2) adhesives, specially suitable for securing sheets of material having a basis of a cellulose derivative to surfaces of glass, cardboard, asbestos, metal, &c., comprising (a) cellulose acetate, resin, acetone, ethyl acetate, and ethyl lactate, (b) cellulose nitrate, camphor, dibutyl phthalate, resin, benzene, alcohol, butyl alcohol, butyl acetate and ethyl acetate; (3) a plastic composition consisting of cellulose acetate, resin, xylene monomethylsulphonamide, alcohol, and benzene; (4) a solution for making filaments by dry spinning methods containing cellulose acetate, resin, and acetone; (5) a lacquer consisting of cellulose acetate, resin, diphenylolpropane, pigment, acetone, ethyl acetate, benzene, toluene, and ethyl lactate. In each of the examples the resin employed is a phenol-chlorketone resin and the proportions of the constituents are given.  The Specification as open to inspection under Sect. 91 (3) (a) also describes the use of a solution of the resin alone as an adhesive. This subject matter does not appear in the Specification as accepted.ALSO:Plastic materials and adhesives are prepared by incorporating a phenol-chlorketone resin with a cellulose derivative, with or without the addition of solvents, plasticizers, softeners, other resins, fire retardants, &c.
