Title: Cellulose ester or ether compositions
IPC: C08K5/06
Filed: 1932-06-27
Abstract: Cellulose ester and ether lacquers &c. are prepared with the aid of bis-b -aryloxyethyl ethers as plasticisers.  Examples are given of the preparation of coating compositions comprising ethyl cellulose and bis-b -cresyloxyethyl ether, and cellulose nitrate, bis-b -chlorophenoxyethyl ether, damar, castor oil and pigment, and cellulose nitrate, bis-b -p-xylyloxyethyl ether and pigment. The plasticisers mentioned may also be used with benzyl cellulose, cellulose acetate &c., and they may be in part replaced by known plasticisers.  The compositions may contain damar in other resins, for example, those of the polyhydric alcohol-polybasic acid and phenol-formaldehyde types.ALSO:Cellulose ester and ether compositions, lacquers &c. are prepared with the aid of bis-b -aryloxyethyl ethers as plasticisers.  The ethers in question are obtained by condensing in the presence of alkali metal hydroxide b b <1>-dichlorodiethyl ether with a phenol or a naphthol or a substituted phenol or naphthol, for example, those containing methyl, ethyl, phenyl or cyclohexyl radicles, or halogens, or alkoxy, carbalkoxy, hydroxyl or carboxyl groups.  Examples are given of the preparation of coating compositions comprising ethyl cellulose and bis-b -cresyloxyethyl ether, and cellulose nitrate, bis-b -chlorophenoxyethyl ether, damar, castor oil and pigment, and cellulose nitrate, bis-b -p-xylyloxyethyl ether and pigment; and of plastic compositions comprising cellulose nitrate and bis-b -o-chlorophenoxyethyl ether, and ethyl cellulose and bis-b -p-xylyloxyethyl ether, and benzyl cellulose and bis-b -o-methoxyphenoxy ethyl ether.  The plasticisers mentioned may also be used with cellulose acetate &c., and they may be in part replaced by known plasticisers.  Other resins may also be employed, such as the polyhydric alcohol-polybasic acid and phenol-formaldehyde resins. The plastic compositions may be used for the manufacture of articles, sheeting, safety glass, rods, tubes &c.  Generally the compositions are of superior flexibility which is retained indefinitely, and of high water resistance.  The Specification as open to inspection under Sect. 91 contains examples of the preparation of bis-b -cresyloxyethyl ether, bis-b -o-methoxy-phenoxyethyl ether, bis-b -o-chlorophenoxyethyl ether and bis-b -p-xylyloxyethyl ether.  This subject-matter does not appear in the Specification as accepted.ALSO:Cellulose ester and ether compositions are prepared with the aid of bis-b -aryloxyethyl ethers as plasticisers.
