    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: 1355008 Moulding compositions FARBWERKE HOECHST AG 23 Feb 1972 [1 March 1971] 8298/72 Headings C3R and C3P A thermoplastic moulding composition comprises (a) 95-40% by weight, based on the composition, of a linear saturated polyester derived from an aromatic dicarboxylic acid and 65-98% be weight, based on the total diols, of ethylene glycol and 2-35% by weight of a diol of the formula in which R 1 is hydrogen or a C 1 -C 4 aliphatic radical and R 2 is a C 1 -C 4 aliphatic radical, and (b) 5-60% by weight, based on the composition, of a copolymer of 92À5-77% by weight of styrene and 7À5-23% by weight of acrylonitrile, the composition having a reduced specific viscosity (measured in a 1% solution of phenol/tetrachloroethane 60 : 40 at 25‹ C.) of at least 0À9 dl/g and a moisture content of less than 0À02% by weight. The examples describe compositions containing a polyester derived from terephthalic acid, ethylene glycol and 2,2-dimethyl 1,3-propanediol.

    Abstract: 1435162 Flame resistant polyester fibres HOECHST AG 20 July 1973 [22 July 1972] 34663/73 Heading C3R [Also in Division C2] Fibres or filaments are made from a polyester comprising dicarboxylic acid units, diol units and units of the formula in which R is an alkylene, cycloalkylene, arylene or aralkylene radical and R 1 and R 2 are C 1-6 alkyl or an aryl or aralkyl group, and R, R 1 and R 2 may carry substituents or contain hetero atoms. The examples describe fibres of polyesters prepared from dimethyl terephthalate, optionally with dimethyl isophthalate, ethylene glycol or 1,4-butanediol and methylene- or ethylene-di(methylphosphinic acids), phenylene - 1,4 - di(methylphosphinic acid), pxylylene - di(methyl - phosphinic acid), ethylene - 1,2 - di(phenylphosphinic acid)
