Abstract:
The invention relates to polymer compositions for the production of mouldings, in particular spectacles and eye-protection equipment, which comply with the provisions of EN 169 (welder protection standard) and EN 1836/2005 (signal light detection). The compositions and mouldings are in particular processable at temperatures above 265° C., recyclable and have a notched impact strength of at least 65 kJ/cm2, and they comply with the required optical standards mentioned above.
