The invention relates to a polymer mixture based on a polyphenylene ether, a polystyrene and/or a high-impact polystyrene, an agent to improve the impact strength, and talcum. By using a mixture of two linear block copolymers as agent (C), a polymer mixture is obtained having a favourable combination of low gloss, good impact strength and a good flow in the melt.

Polymer mixture based on polyphenylene ether and talcum

The invention provides a low gloss polymer blend comprising an aromatic carbonate without reactive groups, a polymer or copolymer having a reactive epoxygroup and an aromatic carbonate polymer or copolymer having a reactive group which react with the epoxy group. Optionally, the composition may contain further usual compounds, such as polymeric materials which are normally used to modify the mechanical properties of polycarbonate, particularly rubbery or non-rubbery polymeric materials containing units of a styrene; also additives like colorants, flame retarding agents may be routinely incorporated.

Polymer blend with low gloss

The flame-retardant properties of polymers with an aromatic main chain can be improved by incorporating therein a fluorine compound in combination with a boron compound.
