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 (&#x201c;ppm&#x201d;), 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.

Polyphenylene sulfide polymer compositions and corresponding laser welding applications

Toughened poly(aryl ether sulfone)/poly(aryl ether ketone) blends. The present invention relates to polymer compositions including at least one poly(aryl ether sulfone) (PASS) 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 (TiO), The polymer composition is particularly suitable for use in mobile electronic devices.
