Abstract
Polymer compositions comprising poly(aryl ether ketone)s and graphene materials. In particular, a polymer composition comprising: A) a poly(arylether ketone) and B) 0.1 to 70 wt. %, based on the combined weight of A) and B), of at least one non-tubular graphene material. Use of such polymer compositions for the manufacture of molded or extruded articles. Molded or extruded articles made from such polymer compositions.
