Abstract

By copolymerisation of compounds which are acid or have a hydroxy or epoxy function in a casting resin with a filler contents of between 10 and 80%, moulded parts on a polymethylmethacrylate basis are obtained which pass the B1-test even without addition of fire-retardant agents and in addition present improved mechanical properties.
