Impact modified compositions of high heat resistant amorphous resins

摘要

A thermoplastic resin composition is provided which contains a high heat amorphous resin; a functionalized elastomer compound; and 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 ductility. The composition is useful for making molded articles exhibiting desired physical properties.
