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.

Abstract: A composition comprises a mixture of two or more polymers which have not been externally plasticized, the polymers being compatible with each other and the second order transition temperatures of two of the polymers differing by 10 DEG to 200 DEG C. wherein at least one of the polymers is a copolymer having a chemically heterogeneous composition obtained by copolymerizing two or more monomers characterized by different polymerization speeds. Compositions exemplified are (I) polyvinyl chloride + vinyl chloride octyl acrylate copolymer and (II) polyvinyl acetate + vinyl acetate/dibutyl maleate copolymer + vinyl acetate/butyl acrylate copolymer filled with vermiculite. Specification 871,254 is referred to.ALSO:One or more resilient members are coated with a composition comprising two or more polymers that have not been externally plasticized, the polymeric components being compatible with one another and the second order transition temperatures of two of the components differing by between 10 and 200 DEG C. wherein at least one of the polymeric components is a copolymer having a chemically heterogeneous composition obtained by copolymerizing two or more monomers characterized by different polymerization speeds. In the examples steel plate is covered with (I) and (II) a composition comprising polyvinyl chloride and a vinyl chloride/octyl acrylate copolymer, (III) polyvinyl acetate, vinyl acetate/dibutyl maleate copolymer and vinyl acetate/butyl acrylate copolymer. Fillers and other resins may be added. Specification 871,254 is referred to.
