摘要： Described herein are polyphenylene sulfide (“PPS”) polymers having excellent transparency to infrared (“IR”) radiation. It was surprisingly discovered that PPS polymer composition including PPS polymers having a selected metal ion (Ca, K, and Mg) concentration at least 400 parts per million by weight (“ppm”), had significantly increase IR transparency, relative to corresponding PPS polymer compositions including a PPS polymer having a selected metal ion concentration less than 400 ppm. Additionally, described herein are methods for laser welding the PPS polymer compositions.

摘要： Methods of making a polymer composition, the method including (i) contacting a poly(arylene sulfide) (PAS) with an aqueous solution including zinc ions, preferably during recovery of the PAS following polymerization, and ii) contacting the PAS with an ethylene copolymer impact modifier. Also described are polymer compositions made by the method, and shaped articles including the polymer composition.

摘要： The present invention relates to polymer compositions including at least one poly(aryl ether sulfone) (PAES) polymer, at least one poly(aryletherketone) (PAEK)polymer, and at least one impact modifier (IM). The polymer composition may optionally include at least one aromatic polycarbonate (PC) and/or titanium dioxide (TiO2). The polymer composition is particularly suitable for use in mobile electronic devices.
