ABSTRACT:
Thermoplastic compositions comprising polyphenylene ethers and polyesters, impact-modified by glycidyl (meth)acrylate grafted EPDM and compatibilized by an aromatic polycarbonate exhibit high impact strength alone and when combined with other impact modifiers. Their shear sensitive viscosity properties makes them uniquely suitable for extrusion and blow molding applications.
