    Abstract: 1283637 Polyester moulding composition FARBWERKE HOECHST AG 6 July 1970 [4 July 1969] 32550/70 Heading C3R A thermoplastic moulding composition comprises (a) a linear saturated polyester of an aromatic dicarboxylic acid and optionally up to 10% by weight of an aliphatic dicarboxylic acid, or of a hydroxy carboxylic acid, with a saturated aliphatic or cycloaliphatic diol, (b) from 0À05 to 2% by weight, based on the polyester, of an inert, inorganic solid material having a particle size of less than 5 microns, and (c) from 0À02 to 8% by weight, based on the polyester, of an alkali metal paraffin monosulphonate R 1 SO 3 M in which R 1 is a straight or branched chain alkyl group having 8 to 30 carbon atoms, and M is an alkali metal, and which may contain up to 0À5% by weight, based on the sulphonate, of an alkali metal paraffin disulphonate MO 3 SR 2 SO 3 M, in which R 2 is a straight or branched chain alkylene group having 8 to 30 carbon atoms, and derived from the same paraffin and alkali metal as the mono-sulphonate, or from 0À02 to 8% by weight based on the polyester, of an alkali metal olefin sulphonate R-CH=CHSO 3 M in which R is a straight or branched chain alkyl or aralkyl group having 6 to 28 carbon atoms. Component (b) may be glass powder, talc, kaolin, magnesium oxide, antimony trioxide, titanium dioxide, aluminium oxide, calcium carbonate or calcium magnesium aluminium silicate. The polyester is preferably polyethylene terephthalate or polycyclohexane- 1,4-dimethylol terephthalate.

    Abstract: 1283644 Polyester-based moulding composition FARBWERKE HOECHST AG 9 July 1970 [10 July 1969] 33378/70 Heading C3R A thermoplastic moulding composition comprises a linear saturated polyester of an aromatic dicarboxylic acid and optionally up to 10% by wt. of an aliphatic diacid or a hydroxycarboxylic acid with a saturated aliphatic or cycloaliphatic diol, e.g. polyethylene terephthalate, and an alkali metal salt of a phosphonic acid RPO(OH) 2 , a phosphonic halfester RPO(OR 1 )(OH), a phosphinic acid R 2 PO(OH) or a phosphonous acid RP(OH) 2 where R and R 1 are hydrocarbon radicals of up to 15 carbon atoms, the additive comprising 0À005 to 5 wt. per cent relative to the polyester. The use of the disodium salt of n-hexyl phosphonic acid and the sodium salt of diphenyl phosphinic acid is described in Examples 1 and 2. Paraffin or other wax may be used as a coating on granules of the composition to exclude moisture.
