Abstract

New linear copolyesters, suitable for the manufacture of tough and flexible mouldings, films, and readily-dyeable and elastic fibres contain the residues of (a) an aromatic dicarboxylic acid, (b) a glycol containing 2-12 carbon atoms and (c) a "dimer glycol" obtained by the reduction of a dimerized fatty acid containing 36 carbon atoms or its esters. The copolyesters may also contain up to 20 mol per cent of the residues of an aliphatic dicarboxylic acid containing 4-20 carbon atoms. Specified reactants are:-for (a) -terephthalic, 4: 41-sulphonyldibenzoic, 4: 41-ethylenedibenzoic, 4: 41-ethylenedioxydibenzoic, 4: 41-diphenic and trans-cyclohexane-1: 4-dicarboxylic acids; for (b)-polymethylene glycols containing 2-10 carbon atoms, 2: 2-dimethyl-1: 3-propanediol, 1: 3- or 1: 4-cyclohexane-dimethanol, 2: 2: 4: 4-tetramethyl-1: 3-cyclobutanediol and p-xylylene glycol. The copolyesters are made in the usual way by reacting the acids or their esters with the glycols or their esters in the presence of the usual catalysts. The final stage of the polyesterification may be effected in the melt or solid phase. Examples describe the manufacture of copolyesters of:-(1)-(4) terephthalic acid, 1: 4-cyclohexane dimethanol and "dimer glycol"; (5)-(6) terephthalic acid, ethylene glycol and "dimer glycol"; (7) 4: 41-ethylenedioxydibenzoic acid, ethylene glycol and "dimer glycol"; (8) 4: 41-diphenic acid, tetramethylene glycol and "dimer glycol"; (9) 4: 41-sulphonyldibenzoic acid, tetramethylene glycol and "dimer glycol"; (10) terephthalic acid, 2: 2: 4: 4 - tetramethyl - 1: 3 - cyclobutanediol and "dimer glycol"; (11) trans-1: 4-cyclohexane-1: 4-dicarboxylic acid, trans-1: 4-cyclohexanedimethanol and "dimer glycol"; (12) 4: 41-sulphonyldibenzoic acid, sebacic acid, tetramethylene glycol and "dimer glycol." Specifications 777,215, 777,216, 777,217, 777,218, 777,219 and 777,220 are referred to.
