Abstract
Blends of a polyphenylene sulfone (PPSU); a polyphenylene sulfide (PPS); and, a polyetherimide and epoxy. The polyetherimide and epoxy are present in an amount effective to act as a compatibilizer for the polyphenylene sulfone (PPSU) and polyphenylene sulfide (PPS). Methods of compatibilizing a blend of polyphenylene sulfone (PPSU) and polyphenylene sulfide (PPS). The method can include melt mixing a polyphenylene sulfone (PPSU) and a polyetherimide; and melt mixing a polyphenylene sulfide (PPS) and an epoxy.
