MULTILAYER COMPOSITE COMPRISING A LAYER OF IMPACT-RESISTANT POLYMETHYLMETHACRYLATE AND A LAYER OF STYRENE-ACRYLONITRILE COPOLYMER; MOULDED ARTICLES

摘要

Composite materials (VS) comprises at least - a layer (A) which comes into contact with the water, based on a high-impact polymethyl methacrylate thermoplastic (PMMA) (SP) with a Vicat softening pt. (VST; ISO 306) of at least 95 degrees C and a notched impact strength (ISO 1801A) of at least 3.0 kJ/m<2>, and - a layer C based on a high-impact acrylonitrile-styrene copolymer (VP).
