COMPOSITIONS OF POLYPHENYLENE ETHER RESIN AND POLY(TETRA-ALKYL BISPHENOL) HAVING REDUCED MELT VISCOSITY ABSTRACT OF THE DISCLOSURE The melt viscosity of thermoplastic composi- tions of polyphenylene ether resin and rubber modified high impact polystyrene resin is significantly reduced by inclusion of a tetra-alkyl bisphenol polycarbonate resin. The resulting blend can be processed at lower temperatures, and, after molding, exhibits better UV color stability while retaining most important other physical properties. Both the compositions and a method of preparation are described.
