Abstract: Described herein are polyphenylene sulfide (“PPS”) polymer compositions including a low MFR PPS polymer and E-CR glass fibers. It was surprisingly discovered that the PPS polymer compositions had significantly improved retention of tensile strength and tensile elongation after water aging (“water aging performance”), relative to corresponding PPS polymer compositions having E glass fibers instead of the E-CR glass fibers. Moreover, it was also discovered that PPS polymer compositions including E-CR glass fibers in conjunction with a low MFR PPS polymer and a high MFR PPS polymer had unexpected synergies with respect to water aging performance, relative to corresponding polymer compositions including E-CR glass fibers and either a low MFR PPS polymer or a high MFR PPS. Due at least in part to the improved water aging performance, the PPS polymer compositions can be advantageously incorporated into application settings where the polymer composition is in contact with water.
