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

The present invention relates to high performance polymer compositions and articles made therefrom. In particular, the present invention relates to compositions (C1) comprising from 25 to 59 wt. % of at least one poly(aryl ether sulfone) (PAES), from 1 to 35 wt. % of at least one poly(aryl ether ketone) (PAEK), from 20 to 35 wt. % at least one polyphenylene sulfide (PPS), and from 5 to 50 wt. % of glass fibers, the wt. % being based on the total weight of the polymer composition (C1).

Glass-filled polymer composition comprising a poly(aryl ether sulfone), a poly(aryl ether ketone), at least one polyphenylene sulfide and glass fibers

A polyaryl ether ether composition(C) and methods of uses thereof are herein disclosed. The composition comprises a polymer blend [blend (B)] consisting of: &#x2014;a first polyaryl ether ketone (PAEK-1)and &#x2014;a second polyaryl ether ketone (PAEK-2), wherein the (PAEK-1) is crystalline and exhibits a melting temperature Tof 330&#xb0; C. or higher and the (PAEK-2) is either amorphous or crystalline and exhibits a melting temperature Tof 315&#xb0; C. or lower and wherein the (PAEK-1) constitutes more than 0% wt of blend (B). Composition (C) can be used in particular for the manufacture of coated metal surfaces, in particular for the coating of wires or of (part of) electronic devices.
