Title: COMPOSITION AND THERMOPLASTIC MOLDING COMPOUND HAVING GOOD LOW-TEMPERATURE TOUGHNESS, HIGH GLOSS, AND HIGH PROCESSING STABILITY
Abstract:
The invention relates to a composition for producing a thermoplastic molding compound, wherein the composition contains or consists of the following constituents: A) 30 to 90 wt% of at least one polymer selected from the group consisting of aromatic polycarbonate, aromatic polyester carbonate, and aromatic polyester, B) 5 to 65 wt% of polymer free of epoxide groups, consisting of B1) rubber-modified vinyl (co)polymerizate produced in the emulsion polymerization process with the use of a redox initiator system consisting of an organic oxidant and a reductant and B2) optionally rubber-free vinyl (co)polymerizate, C) 0.5 to 10 wt% of a polymer containing structural elements originating from styrene and from an epoxide-group-containing vinyl monomer, D) 0 to 20 wt% of one or more further additives, wherein component C has a weight ratio of structural elements originating from styrene to structural elements originating from epoxide-group-containing vinyl monomer of 1:100 to 1:1. The invention further relates to a method for producing a molding compound from the composition, to the molding compound itself, to the use of the composition or of the molding compound to produce molded bodies, and to the molded bodies themselves.
