Abstract

The invention relates to mixtures for producing transparent plastic, which mixtures comprise: a) compounds of formulae (I) and (II), wherein R1 independently represents hydrogen or a methyl group, R2 independently represents a linear or branched, aliphatic or cycloaliphatic group or a substituted or unsubstituted aromatic or heteroaromatic group and m and n independently represent an integer ≧0, with m+n>0, b) a prepolymer produced from polymethacrylate and alkyldithiols or polythiols, preferably HS—R3—SH (III), wherein R3 is the same or different from R2 and may have the definition of R2, and c) aromatic vinyl compounds.
