Abstract
L'invention est relative à une structure multicouche comprenant une couche comprenant un PETG contre laquelle adhère au moins une couche d'une composition méthacrylique ayant un indice de fluidité à chaud (23O0C, 3,8kg) allant de 1 à 5 g/10 min comprenant en poids de 30 à 55%, de préférence de 35 à 50%, de particules multicouches dispersées dans respectivement de 45 à 70%, de préférence de 50 à 65%, d'au moins un PMMA. L'invention est aussi relative à un procédé permettant de protéger un PETG consistant à faire adhérer dans l'ordre par coextrusion, par compression à chaud ou par multiinjection une couche comprenant un PETG et au moins une couche d'une composition méthacrylique telle que décrite précédemment.
