Abstract

A polymer composition [composition (C)] comprising: (a) a polyarylene ether ketone (PAEK-1) comprising recurring units deriving from the incorporation of 1,4:3,6-dianhydrohexitols; (b) a poly(biphenylether) sulfone (PPSU-1 ) comprising repeating units of formula (I) and / or (c) a polyetherimide (PEI-1) comprising repeating units of formula (II) wherein Ar* and Ar*' are as defined in the specification are herein disclosed. (PAEK-1) and (PPSU-1) and / or (PEI-1) are completely miscible and give rise to compositions that are transparent and possess high strength and stiffness and that are suitablefor the manufacture of a variety of shaped articles.
