The present invention relates to a composition (C) comprising a polymer blend including a polyarylether sulfone polymer and a polyarylene sulfide polymer and to an article including said composition.

Polymer compositions including polysulfones and articles made therefrom

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(biphenyl ether) 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 suitable for the manufacture of a variety of shaped articles. 

Polymer compositions based on a bio-sourced polyarylene ether ketone

A polymeric thrust bearing is provided for an ultra-high PV environment. The polymeric thrust bearing includes an annular bearing body having an inner perimeter and an outer perimeter, and a plurality of lubricant channels extending across the annular bearing body from the inner perimeter to the outer perimeter. The annular bearing body comprises a polymer composition comprising a polymer having typically a glass transition temperature of at least about 140&#xb0; C., such as an aromatic polyimide or a poly(aryl ether ketone), and at least one friction and wear additive. The polymeric thrust bearing is configured to withstand a velocity and a pressure in a lubricated environment in which the product of the velocity and the pressure is about 1,100,000 psi-fpm (23540 kg/cm&#xd7;m/min) or more.
