Title: Improvements in or relating to compositions and articles comprising cellulose derivatives
IPC: C08L61/02
Filed: 1933-04-13
Abstract: Liquid, solid or plastic compositions are prepared containing a cellulose derivative and a synthetic resin obtained by the polymerisation of condensation product of an aromatic aldehyde and a ketone.  Suitable aldehydes include benzaldehyde and alkyl, amino and halogen derivatives thereof, such as aminobenzaldehyde and cinnamic aldehyde whilst suitable ketones include the lower fatty ketones such as acetone, methyl ethyl and diethyl ketone. The polymerisation may be effected by heat in the presence or absence of an alkaline catalyst such as sodium or potassium hydroxides.  The derivatives of cellulose that may be used include cellulose nitrate, cellulose organic esters such as cellulose acetate, formate, propionate or butyrate and cellulose ethers such as ethyl, methyl and benzyl cellulose.  The composition may also contain volatile solvents such as acetone, alcohol, benzene, ethylformal or ethylene dichloride; medium or high boiling solvents such as ethyl acetate, ethyl lactate, tetrachlorethane, formal glycerol, benzyl alcohol or diacetone alcohol; plasticisers such as diphenylol propane, triacetin, dibutyl tartrate, diethyl phthalate, dimethyl phthalate, toluene sulphonamide or monomethylxylene sulphonamide; fire retardants such as bromine derivatives of organic compounds such as brominated tricresyl phosphate; pigments or dyes; natural gums or resins such as manila, acaroides, pontianak, kauri, dammar, rosin and shellac; semi-synthetic resins such as ester gum; and synthetic resins such as the fusible and soluble phenol-formaldehyde or diphenylolpropane formaldehyde resins prepared preferably in the presence of acid catalysts.  The liquid compositions may be used as lacquers and coating compositions for metal or glass, in the manufacture of photographic and other films, and as adhesives especially in the manufacture of spinterless glass by causing celluloid sheets to adhere to surfaces of sheets of glass. Artificial yarns may be formed by extruding solutions through the orifices of a spinneret into a heated evaporative atmosphere or into a precipitating bath.  The plastic compositions may be worked into sheets or blocks in any known manner.  The sheets may be used in the manufacture of splinterless glass.  In the examples a benzaldehyde-acetone synthetic resin is used.  In examples: (1) a coating composition is prepared containing cellulose acetate, synthetic resin and acetone; (2) a coating composition containing cellulose acetate, synthetic resin, acetone, benzene, alcohol and diacetone alcohol; (3) an adhesive particularly useful for causing a sheet of cellulose ester plastic to adhere to surfaces of glass, cardboard, asbestos or metal containing cellulose acetate, synthetic resin, acetone, ethyl acetate and lactate; (4) a plastic composition containing cellulose acetate, synthetic resin, monomethylxylene sulphonamide, alcohol and benzene; (5) a solution for use in the manufacture of artificial yarns containing cellulose acetate, synthetic resin and acetone; (6) a pigmented lacquer containing cellulose acetate, synthetic resin, diphenylolpropane, pigment, acetone, ethyl acetate, benzene, toluene and ethyl lactate; (7a) a coating composition containing cellulose nitrate, camphor, diethyl phthalate, synthetic resin, benzene, alcohol, butyl alcohol, butyl acetate and ethyl acetate; and (7b) an adhesive for use in preparation of laminated glass containing cellulose nitrate, camphor, dibutyl phthalate, synthetic resin, benzene, alcohol, butyl alcohol, butyl acetate and ethyl acetate.  In the examples, cellulose acetate may be replaced by cellulose propionate or butyrate and either cellulose acetate or nitrate by cellulose ethers.ALSO:Liquid, solid, or plastic compositions are prepared containing a cellulose derivative and a synthetic resin obtained by the polymerisation of condensation product of an aromatic aldehyde and a ketone.
