| abstract | 1463106 Water-soluble polyamides EASTMAN KODAK CO 4 June 1974 [4 June 1973 20 March 1974] 24729/74 Heading C3R [Also in Division D1] A water-soluble polyamide is derived from (A) adipic, pimelic, or suberic acid; (B) an aliphatic diamine, #95% mole of which is H 2 NC 3 H 6 -(OR) n -O-C 3 H 6 NH 2 where R is ethylene or 1,2- or 1,3-propylene, and n is 2-13; where # inh is 0À15-1À0, and alkyleneoxy/ amide linkage ratio is from 3 : 2 to 14 : 2. Also present may be (C) #25% mole C 9 dicarboxylic acid (1) or #15% mole 1,12-dodecanedioic acid (2), where total (A+C)=100% mole. (B) may also comprise #5% mole or H 2 N(CH 2 ) n NH 2 where n is 3-10, or 1,4-(cyclohexane)bis- (methylamine). (1) may be, e.g. azelaic or 4,4- dimethylpimelic acid. To form the polyamide, the components may be reacted in the form of "polyamide salts" or the acid may be in the form of an anhydride, halide, or ester. #5% mole monofunctional chain-terminators may be present. The polyamide can be used as a hot melt to provide an adhesive layer on a paper or cardboard article or to size a fibrous article, e.g. a yarn of polyester, cotton, rayon, cellulose acetate, nylon, and/or polypropylene. Or an aq. solution of the polyamide may be applied to a substrate to form an adherent coating. A film of the polymer may be used as package for detergents &c., the package disintegrating in hot water. In a comparative example, azelaic acid is used in place of (A), and a water-insoluble polymer results. |
