Title: Improvements in or relating to cellulosic compositions
IPC: C08K5/43
Filed: 1933-04-18
Abstract: Solid, liquid, or plastic compositions comprise a cellulose derivative and a sulphonamide of a phenol ether.  Sulphonamides of ethers derived from phenols, cresols, naphthols, or the like by replacing the hydrogen of one or more --OH groups by an alkyl, aryl, or aralkyl group, for example sulphonamides of anisol, phenetol, ethyl or methyl ethers of d-or b -naphthol, resorcinol, or pyrocatechol, or diaryl ethers such as diphenyl ether, may be used. The amino group may contain one or more substituent groups as in phenol ether methyl-, ethyl-, dimethyl-, diethyl- and methyl-ethyl-sulphonamides, or anisol ethyl sulphonamides.  The sulphonamides may be prepared by reacting the corresponding phenol ethers with sulphuric acid, forming the sodium or potassium salts of the sulphonic acids produced, treating these with phosphorus pentachloride and then with ammonia or substituted ammonia. Inorganic cellulose derivatives such as the nitrate, or organic derivatives such as esters and ethers may be employed.  The composition may be moulded, or solutions may be evaporated or precipitated to form artificial filaments, threads, yarns and other textile materials, or films which may be employed in photography or the manufacture of laminated glass.  Solutions in appropriate solvent mixtures may form the basis of lacquers and other coating compositions, and compatible resins may be added. Where cellulose acetate is employed, the proportion of sulphonamide may vary from less than 25 per cent to more than 50 per cent of the weight of the former.  Mixtures of phenol ether sulphonamides with one another or with other placticizers such as triacetin, dibenzyl-, diethyl-, or dibutyl tartrate, or diethyl phthalate may be employed.  Solvents specified are acetone, methyl acetate, ethylene formal, ethyl lactate, formal glycerol, and diacetone alcohol.  Pigments, fillers, or dyes may be incorporated.  According to examples, a coating composition consists of cellulose acetate, anisol sulphonamide, and acetone, and a lacquer contains in addition a resin of the diphenylol formaldehyde type, alcohol, benzene, and diacetone alcohol.ALSO:Solid, liquid, or plastic compositions comprise a cellulose derivative and a sulphonamide of a phenol ether.
