Title (EN) POLYMER COMPOSITION
(FR) COMPOSITION POLYMÈRE
Abstract:
(EN) The invention relates to a composition with improved scratch and/or abrasion resistance and methods of their manufacture. Compositions for injection moulding, extrusion, (co)extrusion and/or thermoforming are described. The composition comprises (a) an acrylic (co)polymer and (b) a fatty acid amide. At least 30wt% of the acrylic (co)polymer residues are residues of an alkacrylic acid or ester monomer such as methyl methacrylate and 0 to 70wt% are residues of one or more other vinyl comonomers. A process for the production of a composition comprising the steps of melt blending the fatty acid amide with the acrylic (co)polymer or adding the fatty acid amide to the monomer during production of the acrylic (co)polymer. Use of the composition may be in injection moulding, extrusion or co-extrusion. Co-extruded laminates comprising a cap layer of the composition are also described.
(FR) L'invention concerne une composition présentant une résistance améliorée aux rayures et/ou à l'abrasion et des procédés de fabrication de celle-ci. L'invention concerne également des compositions pour le moulage par injection, extrusion, (co) extrusion et/ou thermoformage. La composition comprend (a) un (co)polymère acrylique et (b) un amide d'acide gras. Au moins 30 % en poids des résidus (co)polymères acryliques sont des résidus d'un acide acrylique ou d'un monomère ester tel que le méthacrylate de méthyle et 0 à 70 % en poids sont des résidus d'un ou de plusieurs autres comonomères de vinyle. L'invention concerne également un procédé de production d'une composition comprenant les étapes consistant à mélanger en fusion l'amide d'acide gras avec le (co)polymère acrylique ou à ajouter l'amide d'acide gras au monomère pendant la production du (co)polymère acrylique. La composition peut être utilisée dans le moulage par injection, l'extrusion ou la co-extrusion. L'invention concerne également des stratifiés co-extrudés comprenant une couche de recouvrement de la composition.
