<p>The antiliming thermoplastic methacrylic polymer material comprises the following (a) 95 - 100 % wt. %, preferably 96 99.9 % of a matrix (a1) formed from a polyfluoridized methacrylic copolymer material comprising (1) 50 - 99 wt. %, preferably 70 -96 wt. % methyl methacrylate motifs (2), 0 - 20 wt. %, preferably 2 -15 wt. %, units derived from at least one monoethylenically unsaturated non fluoridized monomer, and (3) 1 -30 wt. %, preferably 2 - 15 % units derived from at least one acrylic and/or polyfluoridized methacrylic monomer or (a2) a mixture formed from (i) 70 99 wt %, preferably 85 -98 wt. % non fluoridized methacrylic (co)polymer comprising 80 - 100 wt. %, preferably 85 -98 wt. % methyl methacrylate units and 0 - 20 wt., preferably 2 -15 wt. % units derived from at least one non-fluoridized monoethylenically unsaturated monomer and (ii) 1 -30 wt. %, preferably 2 - 15 wt. % acrylic (co)polymer and/or polyfluoridized methacrylic (co)polymer comprising units derived from at least one acrylic monomer and/or polyflurodized methacrylic monomer and (b) 0 - 5 wt. %, preferably 0.1 - 4 wt. %, pigment paste and/or colorant dispersed in the matrix.</p> |
