The present invention relates a mobile electronic device comprising at least one part made of a polymer composition comprising for more than 80% by weight (% wt.) relative to the total weight of the composition (C) of an aromatic polysulfone polymer comprising a residual chlorine content in an amount of less than 25 &#x3bc;eq/g polymer.

Mobile electronic devices made of low-chlorine aromatic polysulfones

A polymer composition comprising: at least one polycondensation polymer having a heat deflection temperature (HDT) of above 80&#xb0; C. under a load of 1.82 MPa when measured according to ASTM D648 [polymer (P)]; at least one perfluoropolyether block copolymer [polymer (F)] comprising: A) one or more (per)fluoropolyoxyalkylene segment (chain R) comprising recurring units having at least one catenary ether bond and at least one fluorocarbon moiety, and B) one or more polyalkylene segment (chain R) comprising recurring units of formula: &#x2014;(CRR&#x2014;CRR)&#x2014;; wherein R, R, R, R, equal to or different from each other, are selected from the group consisting of H, halogens; C-C(hydro)carbon groups, optionally containing fluorine or other heteroatoms, to a process for its manufacture and to its use for manufacturing shaped articles, in particular by extrusion molding or injection molding techniques.

Polymer composition

A polysulfone having a first polyphenylene sulfone unit (i.e. PPSU unit) based on one biphenol group and one diphenyl sulfone group and a second sulfone unit (i.e. PSU-AF unit) based on one hexafluorobisphenol A group and one diphenylsulfone group. The polysulfone is transparent and has a total heat release and peak heat release of less than 65 kW&#xb7;min/mand 65 kW/m, respectively. Compositions containing the polysulfone and articles made by molding and/or extruding the polysulfone.
