Patent GB-417871-A (GB)
Title: Improvements in or relating to cellulosic compositions
IPC: C08K5/43
Filed: 1933-04-13
Abstract: Naphthalene sulphonamides are used as plasticizers in compositions containing organic derivatives of cellulose.  Simple sulphonamides of the formula C10H7.SO2,NH2, their nuclea substitution products containing, for example, ethyl, methyl, amino, or hydroxy groups, or derivatives in which the amino group contains one or more substituent groups may be employed.  Naphthalene methyl-, ethyl-, dimethyl-, diethyl-, and methyl ethyl sulphonamides are referred to.  The sulphonamides may be prepared by reacting the sodium salts of the naphthalene sulphonic acids with phosphorus pentachloride and treating the resulting sulphochlorides with ammonia or a substituted ammonia such as ethylamine.  The cellulose derivatives may be esters or ethers.  The compositions may be solid, liquid, or plastic and may be moulded, or formed into threads, yarns, and other textile materials, or into photographic or other films, for example for making laminated glass.  They may form the basis of lacquers and other coating compositions, and compatible resins may be incorporated.  Other plasticizers such as triacetin, dibenzyl-, diethyl- or dibutyl tartrate, and diethyl phthalate may be added. Suitable solvents include acetone, methyl acetate, ethylene formal, ethyl lactate, formal glycerol, and diacetone alcohol.  Pigments, fillers, or dyes may be incorporated.  Examples are given of a coating composition and a lacquer comprising cellulose acetate, a -naphthalene sulphonamide, and solvents and, in the latter case only, a synthetic resin of the diphenylol formaldehyde type.ALSO:Naphthalene sulphonamides are used as plasticizers in compositions containing organic derivatives of cellulose.
