Title: Improvements in or relating to cellulosic compositions
IPC: C08K5/43

Abstract: Benzoyl derivatives of aryl sulphonamides are used as plasticizers in compositions containing organic derivatives of cellulose.  These compounds have the general formula R.SO2.NH.OC.C6H5, where R is an aromatic residue, of benzene, toluene, or xylene, for example, or a nuclear substitution product thereof containing for instance alkyl, amino, hydroxy groups or halogens.  Paratoluene benzoyl sulphonamide is especially suitable and is made by reacting benzoyl chloride with para-toluene sulphonamide.  The cellulose derivatives may be esters or ethers.  The compositions may be solid, liquid, or plastic and may be moulded, formed into filaments, threads and yarns, or into films for photographic purposes or the manufacture of 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, or 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 including cellulose acetate, para-toluene benzoyl sulphonamide, and solvents and, in the latter case only, a synthetic resin of the diphenylol-formaldehyde type.ALSO:Benzoyl derivatives of aryl sulphonamides are used as plasticizers in compositions containing organic derivatives of cellulose.
