FIELD: polymer materials. ^ SUBSTANCE: invention relates to compositions containing thermoplastic polymers and benzotriazoles as UV absorbers as well as to products obtained from these compositions. These products are, in particular, layered plates with their one or both outside layers containing composition made up of polycarbonate, between 0.1 and 15% of one or several different compounds having general formula I: (I) and between 0.0001 and 0.4% of one or several different compounds having general formula II: (II). ^ EFFECT: improved quality of plate surface obtained using extrusion technique due to optimized compositions while preserving required anti-UV protection of plates. ^ 8 cl, 1 tbl |
