Laminate consists of at least two bonded layers, the first layer contg. at least 30% wt. of a styrene polymer (I) with a good thermal stability, and the second layer contg. a styrene polymer other than polymer (I). Specif. the styrene polymer (I) consists of a copolymer of 95-50% wt. styrene and 5-50% wt. maleic anhydride, fumaric anhydride or itaconic anhydride, of 90-20% wt. styrene and 10-80% wt, alpha-methylstyrene, of 90-50% wt. styrene and 10-90% wt. methyl methacrylate of 90-50% wt. alpha-methylstyrene and 10-50% wt. acrylonitrile, or a terpolymer of styrene/alpha-methylstyrene/acrylonitrile, or styrene/methyl methacrylate/alpha-methylstyrene, or styrene/acrylonitrile/maleic anhydride, or styrene/methyl methacrylate/maleic anhydride. The laminates have a combination of lhigh thermal stability, and high rigidity, resistance to impacts, resistance to scratching and/or resistance to solvents, which cannot be obtained with the individual styrene polymers. |
