Title: New plastic compositions
IPC: C08K5/10
Filed: 1947-09-08
Abstract: Natural resins are plasticized by a mixture of a nonyl ester of a monobasic organic acid and a nonyl ester of a polybasic organic acid. Of the former acids formic, acetic, propionic, butyric, methacrylic, hexoic, oleic, stearic, lauric, ricinoleic, abietic, benzoic, and chlorbenzoic acids are specified, and polybasic acids specified are phthalic, adipic, subacic, succinic, tartaric, glycollic, citric, aconitic and tricarballylic acids.  Chlorinated paraffin wax, fillers, stabilizers and colouring matter may be added and the compositions used in lacquers or for making shaped articles. Specifications 500,298, [Group IV], 521,093, [Group V], 573,840, 573,841, 579,550, [all in Group IV], 591,611, 600,270, [Group V], 632,757 and 632,758 are referred to.ALSO:Organic thermoplastic substances are plasticised by a mixture of a nonyl ester of a monobasic organic acid and a nonyl ester of a polybasic acid. Cellulose nitrate, acetate, acetobutyrate, or acetopropionate, ethyl and benzyl cellulose, polymers and interpolymers of vinyl chloride or acetate, vinylidene chloride, methyl methacrylate or acrylonitrile, rubbery copolymers of butadiene with styrene or acrylonitrile, polyvinyl acetals, e.g. the butyral, and halogenated polythene are specified.  Monobasic acids specified are formic, stearic, methacrylic, oleic, ricinoleic, lauric, acetic, propionic, butyric, hexoic, abietic, benzoic and chlorbenzoic acids, and polybasic acids specified are phthalic, adipic, sebacic, succinic, tartaric, glycollic, citric, aconitic, and tricarballylic acids.  The nonyl alcohol preferred is 3,5,5-trimethyl-1-hexanol.  Mixed esters of the polybasic acids may be used, the other alcohol having 4-8 carbon atoms, e.g. 2-ethyl hexanol.  Chlorinated paraffin wax, fillers, stabilisers and colouring matter may be added, and the composition used in coating cables, lacquers and shaped articles.  In the examples, polyvinyl chloride is mixed with the two nonyl esters and either white lead, titanium dioxide and ethyl palmitate or china clay, white lead, carbon black and ethyl palmitate; nitrocellulose is cast into a film from a solution comprising butyl acetate, butyl alcohol, toluene and two nonyl esters.  Specifications 500,298, 521,093, [Group V], 573,840, 573,841, 579,550, 591,611, 600,270, [Group V], 632,757 and 632,758 are referred to.ALSO:Synthetic rubber such as Neoprene and rubbery copolymers of butadiene with styrene and acrylonitrile are plasticized by a mixture of a nonyl ester of a monobasic organic acid and a nonyl ester of a polybasic organic acid. Monobasic acids specified are formic, acetic, stearic, methacrylic, oleie, ricinoleic, lauric, propionic, butyric, hexoic, abietic, benzoic and chlorbenzoic acids, and polybanic acids specified are phthalic, adipic, sebacic, succinic, tartaric, glycollic, citric, aconitic and tricarballylic acids.  Chlorinated paraffin wax, fillers, stabilisers, other plasticizers and colouring matter may be added. Specification 500,298, [Group IV], 521,093; 573,840, 573,841, 579,550, [all in Group IV], 591,611, 600,270, 632,757 and 632,758 are referred to.
