The present invention relates to a process for preparing a polysulfone (PSU) polymer having a low yellowness index (YI). The present disclosure also relates to a PSU obtained from this process, as well as to articles incorporating this PSU.

Process for preparing a polysulfone (PSU) polymer

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 comprising sulfone groups, ketone groups and optionally substituted polyarylene groups, wherein the number of moles of sulfone groups over the number of moles of ketone groups ratio is greater than 1. A process for making such polymer, a composition comprising such polymer, and articles made therefrom.
