Abstract: A mobile electronic part comprising: (i) a shaped metal part, at least part of the surface thereof being coated with at least one polymer layer (L), wherein the metal is selected from a group consisting of magnesium, aluminum and alloys of these metals, and wherein said polymer layer (L) comprises at least one polymer selected from an aromatic polyamide-imide polymer [(PAI) polymer, herein after] or a poly(ethersulfone) polymer [(PESU) polymer herein after], and (ii) a thermoplastic resin composition layer [layer (T), herein after] fixed to the at least one polymer layer (L) of said shaped metal part wherein said composition comprises at least one thermoplastic polymer [polymer (T), herein after].

Abstract: A polyarylene composition containing one or more polyarylenes and one or more sterically hindered phenolic stabilizers. The polyarylene composition has enhanced resistance to discoloration and degradation under thermal stress.

Abstract: Fasteners, such as bolts, nuts and screws, rivets, pins, and retaining rings, made of a highly kinked rigid-rod polyarylene exhibiting outstanding characteristics, notably a high torque and a high tensile elongation, a measure of practical toughness.

Abstract: Polyarylene compositions including one or more organic substances. The organic substances can be selected from the group consisting of a paraffin, an olefin, an olefin oligomer, an alkoxylated acyclic carboxylic acid, an alkoxylated acyclic carboxylic acid amide, an acyclic carboxylic acid, an acyclic carboxylic acid ester, an acyclic carboxylic acid alkali metal salt, an acyclic carboxylic acid amide, an alkoxylated acyclic alcohol, an acyclic alcohol, an alkoxylated alkyl phenol and an alkyl phenol. The organic substances provide improved processability. Further inclusion of a sterically hindered phenol provides tougher polyarylene compositions.
