Copolyestercarbonate and polycarbonate

The invention relates to a mixture of a polyphenylene ether resin and a styrene-containing polymer or copolymer, in which at least a part of the polyphenylene ether resin is modified with reactive groups of a first type and at least a part of the styrene-containing polymer or copolymer is modified with reactive groups of a second type which are capable of reacting with the reactive groups of the first type. The invention further relates to articles formed from the said mixture, which have a good combination of low surface gloss and mechanical properties.

Polymer mixture which comprises a polyphenylene ether and a

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 invention relates to polymer compositions comprising an aromatic polycarbonate, an aromatic polycarbonate with acid or ester functionality, a styrene based polymer and a styrene polymer with oxazoline groups. The polymer composition of the invention is suitable for molding objects with a mat surface.
