  • Patent number: 9376561
    Abstract: Described herein are polymer compositions comprising at least one inorganic salt comprising a cation selected from the group consisting of alkali metals, alkaline earth metals and aluminum, and an anion selected from the group consisting of chloride, sulfate, nitrate, phosphate, acetate and formate, in a concentration of 100 to 5000 mg/kg, based on the composition, and wherein the salt is present in the composition exclusively in dissolved form or in the form of amorphous and/or crystalline inclusions having a size of not more than 60 ?m. Compositions of the present invention are distinguished by an improved surface after heat-moisture storage and are suitable in particular for the production of moldings with a high gloss finish that demand a class A surface, which have optionally been subjected, in whole or in part, to a further surface treatment step involving e.g. lacquering, in-mold decoration, or metallization by vacuum deposition or galvanization.

  • Publication number: 20160152833
    Abstract: The present invention relates to a coating composition comprising at least 30% by weight of at least one thermoplastic polymer having a mean molar mass of at least 100 000 g/mol, at least one UV-curable reactive diluent, at least one photoinitiator, at least one organic solvent, where the proportion of ethylenically unsaturated groups is at least 3 mol per kg of the solids content of the coating composition. The present invention relates more particularly to a moulding comprising a thermoplastic polymer, a film of a thermoplastic polymer and a surface coating of the film, said surface coating forming the surface of the moulding and having a thickness in the range of ?0.1 ?m and ?20 ?m, obtainable by coating the film with the coating composition. In this way, a non-directionally impact-resistant moulding having a scratch-resistant and solvent-resistant surface is provided.

  • Publication number: 20040176532
    Abstract: A process of producing a graft polymer of the ABS type by the emulsion method is disclosed. In the process wherein 5 to 95% by weight of a monomer mixture that contains A) 50 to 99 parts by weight of at least one vinyl aromatic compound and B) 1 to 50 parts by weight of at least one copolymer is polymerized in the presence of C) 95 to 5% by weight of one or more graft substrates having a glass transition temperature <10° C., the improvement includes monitoring continuously in the course of the reaction the Raman spectra of the reaction mixture, determining deviations from the specified desired course of the reaction and making corresponding adjustments.
