Abstract

L"invention concerne des objets multicouches coextrudés-soufflés améliorés (tels que des réservoirs à carburant) présentant au moins une couche barrière et une couche de support, ainsi que de nouveaux procédés de préparation de tels objets. La couche barrière comprend une quantité d"une polyoléfine modifiée ayant approximativement la même densité que la couche de support. La polyoléfine modifiée est préparée par greffage à la polyoléfine d"un acide carboxylique insaturé ou d"un dérivé dudit acide. La polyoléfine modifiée est ajoutée en quantité telle que la couche étanches aux gaz adhère suffisamment à la couche adjacente et que les propriétés de la couche étanches aux gaz de l"article fabriqué demeurent appropriées. L"invention concerne en outre la modification rhéologique de résines de base, telles que le PET (une matière préférée pour la couche barrière), qui s"adaptent ainsi plus étroitement à la rhéologie du polyéthylène à haute densité (une matière préférée pour la couche de support).
