Abstract: The present invention relates to a fibre composite material W of increased translucency and/or mechanical strength, comprising a copolymer C encompassing monomers A-1, where A-1 form covalent bonds with functional groups B-1 on the surface of fibres B embedded in the fibre composite material W, and this fibre composite material W has greater translucency and/or mechanical strength than a fibre composite material Win which the copolymer C contains no A-1. The present invention further embraces a method for producing a fibre composite material W of increased translucency and/or mechanical strength.

Abstract: A process for the production of a graft copolymer composition is presented, which is based on acrylonitrile-styrene-acrylate (ASA) or acrylonitrile-butadiene-styrene (ABS) graft copolymers. The graft copolymers obtained by emulsion polymerization and precipitation show improved dewatering behavior after precipitation. Based on this method ASA and ABS graft copolymers with low residual humidity can be obtained. Furthermore, the invention relates to a process for the production of a thermoplastic molding composition comprising at least one thermoplastic styrene copolymer, in particular a styrene-acrylonitrile copolymer, the graft copolymer obtained by the process, and optional further components.
