IPC: C08K5/01

Abstract: Plastic and elastic masses and solutions are obtained by mixing alkyl or aralkyl ethers of cellulose, or of its derivatives or conversion products, with the viscous oily liquids prepared according to Specification 149,317, [Class 91, Oils &c.], and obtained when acetylene reacts in the presence of aluminium chloride with the hydrocarbons occurring in tar oils and possessing a boiling point about 140 DEG  C.  Mixing may be effected with or without the aid of a volatile solvent such as benzene, benzene-alcohol, carbon tetrachloride, chloroform, chloroform-alcohol, acetone, or acetone-alcohol; and to the mixture may be added other plastic substances or agglutinants such as cellulose nitrate, acetate, or other esters, and other colloiding or softening agents such as camphor, phosphoric esters of phenols, or animal and vegetable oils, as well as dyes, filling materials, and inorganic or organic pigments.  The products obtained may be used as substitutes for india-rubber &c., and in the manufacture of artificial leather, films, photographic articles and coatings, lacquers, varnishes, paints, electric insulating material, dressings for fabrics, leather, paper &c., sizing and coating materials, printing and thickening materials for pigments, artificial thread or hair, adhesives, and cements. In examples, a celluloid is prepared from a viscous liquid as above-mentioned, and a water-insoluble ethyl- or benzyl-cellulose or -starch with or without the aid of a solvent for the ether; an artificial leather from a solution containing ethyl cellulose, the viscous liquid in question, and benzene or benzene-alcohol, the solution being applied in one or several layers to fabric or paper; an artificial leather by applying a mixture of ethyl- or benzyl-cellulose or -starch and the viscous liquid with or without a small proportion of solvent; and the last-mentioned composition is also used for the insulation of cables &c. Specifications 6035/13, 6387/13, and 3370/14, [Class 2 (iii), Dyes &c.], are referred to. The Specification as open to inspection under Sect. 91 (3) (a) includes also the application of the process to the aryl ethers of cellulose &c.  This subject-matter does not appear in the Specification as accepted.ALSO:Adhesives; glue; sizes and finishes, are obtained by mixing alkyl, aryl or aralkyl ethers of cellulose, starch, dextrin or other carbohydrates having the empirical formula (C6H10O5) or of their derivatives or conversion products, with the viscous oily liquids prepared according to the process of Specification 149,317, [Class 91, Oils &c.], and obtained when acetylene reacts in the presence of aluminium chloride with the hydrocarbons occurring in tar oils and possessing a boiling point above 140 DEG  C.  Mixing may be effected with or without the aid of a volatile solvent such as benzene, benzene-alcohol, carbon tetrachloride, chloroform, chloroform-alcohol, acetone, or acetone-alcohol; and to the mixture may be added other plastic substances or agglutinants such as cellulose nitrate, acetate or other esters, and other colloiding or softening agents such as camphor, phosphoric esters of phenols, or animal and vegetable oils, as well as dyes, filling materials, and inorganic or organic pigments.  Specifications 6035/13 and 6387/13, [both in Class 2 (ii), Cellulose &c.], and 3370/14 are referred to.  The Specification as open to inspection under Sect. 91 (3) (a) includes also the application of the process to the aryl ethers of cellulose, &c.  This subject-matter does not appear in the Specification as accepted.ALSO:The alkyl or aralkyl ethers of starch, dextrin or other carbohydrates having the empirical formula (C6H10O5) or of their derivatives or conversion products, are converted into plastic masses or solutions by mixing with the viscous oily liquids prepared according to Specification 149,317.  Mixing may be effected with or without the aid of a volatile solvent such as benzene, benzene-alcohol, carbon tetrachloride, chloroform, chloroform-alcohol, acetone, or acetone-alcohol; and to the mixture may be added other plastic substances or agglutinants such as cellulose nitrate, acetate or other esters, and other colloiding or softening agents such as camphor, phosphoric esters of phenols, or animal and vegetable oils, as well as dyes, filling materials, and inorganic or organic pigments.  Specification 3370/14 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) includes also the application of the process to the aryl ethers of starch, &c.  This subject-matter does not appear in the Specification as accepted.ALSO:A thickening-agent for use in printing compositions is obtained by mixing alkyl or aralkyl ethers of cellulose, starch, dextrin or other carbohydrates having the empirical formula (C6H10O5) or of their derivatives or conversion products, with the viscous oily liquids prepared according to Specification 149,317 [Class 91, Oils &c.], and obtained when acetylene reacts in the presence of aluminium chloride with the hydrocarbons occurring in tar oils and possessing a boiling point above 140 DEG  C.  Mixing may be effected with or without the aid of a volatile solvent such as benzene, benzene-alcohol, carbon tetrachloride, chloroform, chloroform-alcohol, acetone, or acetone-alcohol; and to the mixture may be added other plastic substances or agglutinants such as cellulose nitrate, acetate or other esters, and other colloiding or softening agents such as camphor, phosphoric esters of phenols, or animal and vegetable oils, as well as dyes, filling materials, and inorganic or organic pigments.  Specifications 6035/13, 6387/13, and 3370/14 also are referred to.  The Specifications as open to inspection under Sect. 91 (3) (a) includes also the use of the aryl ethers of cellulose, &c.  This subject-matter does not appear in the Specification as accepted.
