Abstract

We have devised and developed a new method for the preparation of a poly(phenylene sulfide)/poly(phenylene ether) (PPS/PPE) alloy, which has micro- dispersed PPE in the PPS matrix. PPS was chemically treated to activate the reactivity of the PPS end-group by extrusion in the presence of diphenylmethane diisocyanate (MDI) in its molten state at 300 degreesC. The reactive processing of tile MDI-treated PPS with maleic anhydride-modified PPE gave aPPS/PPE alloy with micro-dispersed PPE in the PPS matrix. The PPS/PPE alloy showed mechanical properties superior to those of PPS at elevated temperature (150 degreesC) and also showed precision-molding ability superior to that of PPS.
