Abstract: The present invention relates to flame-retardant compositions based on a thermoplastic polyamide comprising non-fibrous and unfoamed ground glass with specific particle size distribution, geometry and size, and also to the production and the use of the compositions of the invention for producing products, preferably fibres, foils and mouldings of any type.

Abstract: This invention relates to thermoplastic molding compositions with improved flowability based on a thermoplastic polyester and on at least one copolymer composed of at least one olefin with at least one methacrylic ester or acrylic ester of an aliphatic alcohol, the MFI of the copolymer being not less than 50 g/10 min, to a process for preparation of these molding compositions, and also the use of these molding compositions for production of moldings for the electrical, electronics, telecommunications, motor vehicle or computer industry, in sports, in the household, in medicine or for the entertainment industry.

Abstract: The invention relates to molded flexible polyamide materials containing polyamide and olefin/vinyl acetate copolymers, films and hollow elements comprising at least one layer of said molded materials, and methods for producing the molded materials, films, and hollow elements.

Abstract: Use of a flame hydrolysis apparatus for preparing fumed silica particles or a plasma torch apparatus for sintering fumed silica particles to fused silica particles is capable of producing highly pure silica with non-silicon metal impurities less than 500 pb, when at least an inner nozzle is constructed of a silicon-containing material having a low level of non-silicon metal impurities. Preferably, all surfaces in the respective apparatus which contact silica are of similar construction. The silica contains a low level of impurities as produced, without requiring further purification.

Abstract: The invention relates to a process for preparing a reaction product (RP) which is functionalized by groups containing halogen or sulfonyl chloride by reaction of at least one free-radically polymerizable monomer, at least one compound of the formula (I), 1

Abstract: The invention relates to a method for improving the adhesion stability of the surface of moulded parts consisting of synthetic material, especially polycarbonate.
