Title (EN) MULTI-LAYER COMPOSITION
(FR) COMPOSITION MULTICOUCHES
Abstract: front page image
(EN)The invention relates to a multi-layer acrylic composition having at least two impact modified layers. The outer layer is an acrylic layer containing impact modifiers having a particle size of less than 225 nm, and the impact modifiers in the inner thermoplastic layer have a particle size of greater than or equal to 225 nm. The invention also relates to multi-layer composites having the multi-layer acrylic composition on one or both sides. The multi-layer acrylic composition can also include blends of acrylic and fluoropolymers.
(FR)L'invention concerne une composition acrylique multicouches possédant au moins deux couches modifiées pour la résistance au choc. La couche externe constitue une couche acrylique contenant des agents antichoc à granulométrie inférieure à 225 nm et les agents antichoc dans la couche thermoplastique interne présentent une granulométrie supérieure ou égale à 225 nm. Ladite invention a aussi pour objet des composites multicouches renfermant la composition acrylique multicouches sur un ou deux côtés. Ladite composition peut, également, contenir des mélanges d'acrylique et de polymères fluorés.
