Abstract
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).
