La présente invention concerne une composition de résine de poly(éther d'arylène) modifiée et, plus spécifiquement : une composition de résine de poly(éther d'arylène) contenant une résine de poly (éther d'arylène), une résine de poly(éther d'arylène) modifiée avec un acide carboxylique insaturé ou un anhydride de celui-ci, une résine de polyamide, une résine à base de polyoléfine et un agent d'encapsulation, la résine à base de polyoléfine étant encapsulée, par l'agent d'encapsulation, avec la résine de poly(éther d'arylène) et la résine de poly(éther d'arylène) modifiée par un acide carboxylique insaturé ou un anhydride de celui-ci; et un produit moulé préparé à partir de celle-ci. Selon la présente invention, il y a un effet à fournir une composition de résine de poly(éther d'arylène) présentant un faible changement de ses propriétés physiques en raison de l'humidité, et ayant une résistance aux chocs, une résistance aux intempéries et un équilibre de propriétés physiques excellents tout en ayant une viscosité spécifique faible.
