A curable composition includes a functionalized poly(arylene ether) resin, an acryloyl monomer, and a phosphorus flame retardant. The composition exhibits an improved balance of properties such as toughness, flame retardance, heat-resistance, and moisture resistance. It is useful, for example, as an encapsulant for semiconductor products.

A method for the production of mechanically stabilized polyazole polymers, comprising the following steps: a) providing a membrane comprising i.) polyazoles with at least one amino group in a repeating unit except the ones obtainable by reacting aromatic and/or heteroaromatic diaminocarboxylic acids, ii.) at least one strong acid and iii.) at least one stabilizing reagent, the total content of stabilizing reagents in the membrane being within the range of from 0.01 to 30% by weight, b) performing the stabilization reaction in the membrane, immediately or in a subsequent processing step of the membrane, c) if appropriate, additionally doping the membrane obtained in accordance with step b) with a strong acid or concentrating the present strong acid further by removal of present water, wherein the stabilizing agent comprises at least one oxazine-based compound. The polyazole polymer membranes thus obtainable are in particular characterized by a high conductivity and a very good mechanical stability. Therefore, they are in particular suited for applications in fuel cells.
