Abstract:
Compositions including a blend of a) a polysulfone (PSU); b) a polyphenylene sulfide (PPS); and, c) a polyetherimide and epoxy. The polyetherimide and epoxy can be present in an amount effective to act as a compatibilizer for the polysulfone (PSU) and polyphenylene sulfide (PPS).Various embodiments relate to a method of compatibilizing a blend of polysulfone (PSU) and polyphenylene sulfide (PPS). The method can include a) melt mixing a polysulfone (PSU) and a polyetherimide; and b) melt mixing a polyphenylene sulfide (PPS) and an epoxy. Step a) and b) can be carried out by one of sequential mixing and simultaneous mixing.
