Abstract

1,232,323. Polyamides. FARBWERKE HOECHST A.G. 11 July, 1969 [11 July, 1968], No. 35073/69. Heading C3R. A polycarbonamide chain contains 0À05-10 mol. per cent, based on monomer units of the unmodified polycarbonamide, of sulphonate salt(s) derived from an aliphatic sulphocarboxylic acid (A) or from a-sulphophenylacetic acid (B), and/or the carboxylic ester (E) of such acid. Acid (A) may have 2-18 C atoms, and may have 1 or 2-SO 3 H gps. and 1 or 2-COOH gps.; it may also contain at least one -OH gp., or alkyl or alkoxy gps. or halogen atoms. (A) may be e.g. a sulphoacetic, propionic, butyric, palmitic, stearic, adipic, vinyl acetic, hydroxybutyric, or disulphoadipic acid. Salt (S) may be the Li, Na, or K sulphonate. Ester (E) may be derived from an aliphatic C 1 -C 6 alcohol. The polycarbonamide-forming starting substances may be the usual aminocarboxylic acids, lactams, and neutral salts of dicarboxylic acids and diamines, e.g. #-amino caproic acid, #- caprolactam and hexamethylene diammonium adipate. In the examples, a mixture of these latter two substances is used. The sulphonates may be added as powdered solid or in aqueous solution before, during, or after the polycondensation. The reaction may be performed under N 2 at up to 270‹ C. in the presence of water and manganese acetate. The product is poured into cold water, chipped, washed, and dried. It may have a rel. vise. 2À7-3-1 (0À2 g. polyamide in 20 ml. 95À5% H 2 SO 4 ). Filaments formed are dyed only slightly by acid dyes, but deeply by basic dyes. The fibres be mixed with unmodified polyamide films and dyed in a single bath with combinations of acid and basic dyes, producing excellent multicolour effects. The filaments may be used for the manufacture of tufted carpets. Films may also be formed. Extraction with hot water to remove low M.W. substances may be performed before or after forming.
