Abstract
Compatibilized blends of poly(phenylene ether) resins and polyester resins are provided from nucleophile containing poly(phenylene ether) resins and polyester resins and compatibilizer compounds to afford articles having good impact, ductility and tensile properties. The compositions may further comprise impact modifiers, metal salts, reinforcing agents, flame retardants and flow promoters. Articles made from the compositions are useful for automotive components. Polymers chain extended with multifunctional orthoesters are claimed.
