Abstract
A composition can be used for producing a PMMA-based cast polymer with a low styrene content using urea (derivatives) as a formulation constituent, and a hydrophilic inorganic compound as a filler. It is possible to produce PMMA-based cast polymers and mouldings having surprisingly high mechanical stability from the composition.
