Abstract
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.
