    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: 1,268,155. Polyester moulding compositions. FARBWERKE HOECHST A.G. 1 July, 1970 [1 July, 1969], No. 31874/70. Heading C3R. A thermoplastic moulding composition comprises a mixture of (a) a linear saturated polyester of an aromatic dicarboxylic acid, and, optionally, a small amount of an aliphatic dicarboxylic acid with a saturated aliphatic or cycloaliphatic diol, or of hydroxycarboxylic acid and (b) sodium fluoride having a particle size of less than 10 microns in an amount of from 0.005 to 5% by weight of the polyester. The polyester is preferably polyethylene terephthalate, a polyethylene terephthalate copolyester or polycyclohexane-1,4-dimethylol terephthalate. The composition may also contain talc or boron nitride as additional nucleating agents; salts and ester salts of montan wax, paraffin sulphates and olefin sulphates as mould release agents or copolymers of ethylene and vinyl acetate, ethylene and acrylic acid ester or butadiene and styrene to improve impact strength. Particles of the composition may be coated with waxes, e.g. paraffin wax to keep the moisture content low.
