Abstract
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 30 wt % of the acrylic (co)polymer residues are residues of an alkacrylic acid or ester monomer such as methyl methacrylate and 0 to 70 wt % 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.
