Stabilized compositions of high heat amorphous resins and functionalized elastomers

摘要

A thermoplastic resin composition is provided which contains a high heat amorphous resin; a functionalized elastomer compound; and a sterically hindered ortho-substituted aryl phosphite compound. The compositions optionally contain a catalyst capable of improving the ductility of the composition; wherein said catalyst and said high heat amorphous resin are melt-mixed prior to the addition of the functionalized elastomer compound. The composition exhibits enhanced physical properties, specifically enhanced color retention and ductility. The composition is useful for making molded articles exhibiting desired physical properties.
