  • Polymer mixture comprising a polyphenylene ether and optionally a polystyrene and/or a rubber-modified polystyrene, and articles formed therefrom
    Patent number: 5288812
    Abstract: Polyphenylene ethers may show the property that their molecular weight increases considerably upon extrusion. This increase of the molecular weight leads to less good flow properties. It has been found that the addition of a conjugated, non-aromatic diene compound or of a dienophilic compound suppresses the increase of the molecular weight under extrusion.
