Abstract

559,028. Cellulose derivative compositions. ENGEL, W. Sept. 16, 1942, No. 13085. [Class 2 (ii)] [Also in Groups VIII and XXIII] A curable thermoplastic composition comprises cellulose nitrate or ethyl cellulose, polyvinyl acetate or a polyvinyl acetate-acetal, a urea- or melamine-formaldehyde resin, and a plasticizer. The plasticizer may be dibutyl phthalate, tricresyl phosphate, or castor oil. When urea-formaldehyde is used, bitumen may be incorporated in the composition to plasticize the urea resin so as to obtain a thermo-setting product which remains somewhat plastic after a heat-condensation treatment. Compounding of the ingredients may be effected by dry mixing, or by dissolving them in solvents and then evaporating the solvents, or by dissolving them in solvents, precipitating the mixture from the solution, and then mechanically working the dough. The composition may be used in sheet form or may be moulded to any desired shape. It may be set by a heat treatment, or if accelerators are present it will set on ageing. The composition may be pressed or calendered into sheet form on or between canvas or other textile fabric and may then be heat cured. Canvas or other textile fabric or paper may be impregnated with solutions of the material. Gaskets and washers may be produced by pressing or calendering the composition in sheet form on to a paper, cardboard or other suitable base, or by impregnating the base, preferably with solutions of increasing viscosity, and curing by heat or lapse of time. The composition may be used to unite the laminations of laminated wood. The laminae of wood impregnated with the composition or sandwiched with layers of the composition, impregnated paper, or layers of paper and composition, are pressed together and heated. Specification 345,521 is referred to.
