POLYMETHACRYLIMIDE PLASTIC FOAM MATERIALS WITH REDUCED INFLAMMABILITY IN ADDITION TO A METHOD FOR THE PRODUCTION THEREOF

摘要

The present invention relates to compositions for producing poly(meth)acrylimide foams having reduced flammability which comprise ammonium polyphosphate and/or zinc sulphide. Furthermore, the present invention also provides poly(meth)acrylimide moulding compositions and also poly(meth)acrylimide foams obtainable from the abovementioned compositions and moulding compositions. The present invention further relates to processes for producing poly(meth)acrylimide foams having reduced flammability.
