A blend comprising a) at least one aromatic nylon with or without inorganic nano-particles and b) at least one aliphatic/aromatic nylon comprising aromatic groups along the polymer backbone in an amount effective to prevent crystallization of the aromatic nylon. The blend reduces crystallization and resulting haze in multilayered products such as bottles, particularly in multilayered products are subjected to steam autoclave sterilization or retorting.
L'invention concerne un mélange comprenant a) au moins un nylon aromatique avec ou sans nanoparticules inorganiques et b) au moins un nylon aliphatique/aromatique comprenant des groupes aromatiques le long du squelette du polymère en quantité efficace pour empêcher la cristallisation du nylon aromatique. Le mélange réduit la cristallisation et le voile résultant dans des produits multicouches tels que des bouteilles, en particulier dans des produits multicouches soumis à une stérilisation à la vapeur dans un autoclave.
