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.

L'invention concerne des compositions de polyarylène comprenant une ou plusieurs substances organiques. Les substances organiques peuvent être choisies dans l'ensemble consistant en une paraffine, une oléfine, un oligomère d'oléfine, un acide carboxylique acyclique alcoxylé, un amide d'acide carboxylique acyclique alcoxylé, un acide carboxylique acyclique, un ester d'acide carboxylique acyclique, un sel de métal alcalin d'acide carboxylique acyclique, un amide d'acide carboxylique acyclique, un alcool acyclique alcoxylé, un alcool acyclique, un alkylphénol alcoxylé et un alkylphénol. Les substances organiques permettent d'améliorer l'aptitude au traitement. L'inclusion supplémentaire d'un phénol stériquement encombré donne des compositions de polyarylène plus résistantes.
