Abstract

Synthetic resins are prepared by condensing a dihydroxybenzophenone with an aldehyde or aldehyde-yielding substance, preferably in the presence of an acid or alkaline catalyst. Examples are given of the condensation of 2 : 4<1>-and 4 : 4<1>-dihydroxybenzophenones with formaldehyde in the presence of hydrochloric acid. Other aldehydic reactants mentioned are acetaldehyde, paraformaldehyde, metaformaldehyde and hexamethylenetetramine. The products are useful for the manufacture of lacquers, varnishes and coating compositions, preferably by incorporating them with a cellulose derivative, with or without the addition of solvents, plasticizers, softeners, other resins, fire retardants, and pigments or dyes. The cellulose derivative may comprise 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 phenol-formaldehyde and diphenylolpropane-formaldehyde resins, and the natural resins manila, acaroid, pontianak, kauri, dammar, rosin, shellac, and ester gums. Brominated organic compounds, such as brominated tricresyl phosphate, are referred to as fire retardants. Examples are given of the preparation of (1) a coating composition consisting of (a) cellulose acetate, the synthetic resin, and acetone, (b) cellulose acetate, the synthetic resin, acetone, benzene, alcohol, and diacetone-alcohol, (c) cellulose nitrate, camphor, diethyl phthalate, the synthetic resin, benzene, alcohol, butyl alcohol, butyl acetate and ethyl acetate; (2) a pigmented lacquer made of cellulose acetate, the synthetic resin, diphenylolpropane, pigment, acetone, ethyl acetate, benzene, toluene and ethyl lactate.ALSO:Synthetic resins are prepared by condensing a dihydroxybenzophenone with an aldehyde or aldehyde-yielding substance, preferably in the presence of an acid or alkaline catalyst.

Other aldehydic reactants mentioned are acetaldehyde, paraformaldehyde, metaformaldehyde and hexamethylenetetramine. The products are useful for the manufacture of lacquers, varnishes, coating compositions, adhesives, plastics, films and filaments, preferably by incorporating them with a cellulose derivative, with or without the addition of solvents, plasticizers, softeners, other resins, fire retardants, and pigments or dyes. The cellulose derivative may comprise the nitrate, acetate, formate, propionate, butyrate or other ester, or ethyl cellulose, methyl cellulose, benzyl cellulose, or other ether.

Examples are given of the preparation of (1) a coating composition consisting of (a) cellulose acetate, the synthetic resin, and acetone, (b) cellulose acetate, the synthetic resin, acetone, benzene, alcohol, and diacetonealcohol, (c) cellulose nitrate, camphor, diethyl phthalate, the synthetic resin, benzene, alcohol, butyl alcohol, butyl acetate and ethyl acetate; (2) adhesives, particularly suitable for securing sheets of material having a basis of a cellulose derivative to the surfaces of glass, cardboard, asbestos and metal, e.g. for securing the reinforcing layer to the glass in reinforced glass, comprising (a) cellulose acetate, the synthetic resin, acetone, ethyl acetate and ethyl lactate, (b) cellulose nitrate, camphor, dibutyl phthalate, the synthetic resin, benzene, alcohol, butyl alcohol, butyl acetate and ethyl acetate; (3) a plastic composition consisting of cellulose acetate, the synthetic resin, xylene monomethylsulphonamide, alcohol, and benzene; (4) a solution for making artificial filaments by dry spinning methods by dissolving cellulose acetate and the synthetic resin in acetone; (5) a pigmented lacquer made of cellulose acetate, the synthetic resin, diphenylolpropane, pigment, acetone, ethyl acetate, benzene, toluene and ethyl lactate. In each of the examples the proportions are given. The Specification also states that artificial filaments may be made by wet spinning methods, that a solution containing the synthetic resin alone may be used as an adhesive, particularly for securing cellulose derivative sheets to sheets of glass in the manufacture of reinforced glass, and that plastic compositions containing a cellulose derivative and the synthetic resin may be worked into sheets for use in the manufacture of reinforced glass.ALSO:Synthetic resins are prepared by condensing a dihydroxybenzophenone with an aldehyde or aldehyde-yielding substance, preferably in the presence of an acid or alkaline catalyst.
