Abstract

The invention relates to novel poly(meth)acrylates for producing moulding compositions. In particular, the invention relates to novel methacrylates having ester groups which, in the cleavage process, liberate at most only a very small amount of components which are not re-copolymerizable. Copolymerization of monomers of this type in the production of the novel poly(meth)acrylates for moulding compositions brings about only minimal alteration of the heat resistance of these materials or may indeed improve the same.
