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

Polyamides are made from the polycondensation of monomers including from 15 to 80 mol % of 2,5-furandicarboxylic acid (FDCA), from 20 to 85 mol % of at least one aromatic dicarboxylic acid and from 50 to 100 mol % of at least one aliphatic diamine selected from those including 6 and 7 carbon atoms. A process allowing the synthesis of high molecular weight polyamides made from the above mentioned monomers is also described. Finally, compositions and articles including the same polyamides are also disclosed.
