Patent number: 4680329Abstract: Polyphenylene ether resin compositions, optionally also containing polystyrenes, with improved impact properties and resistance to stress-cracking and delamination are prepared by blending with said resin at least one hydrocarbon polymer containing phosphorus acid or derivative (preferably phosphonate) groups and at least one fatty acid salt such as zinc stearate. Preferably, there are added to the blend at least one plasticizer (especially a triaryl phosphate) and at least one aromatic polymer containing acidic (especially sulfonic acid) substituents or salts thereof.Type: GrantFiled: August 19, 1985Date of Patent: July 14, 1987Assignee: General Electric CompanyInventors: Sterling B. Brown, Dennis J. McFay
