Abstract
The invention relates to mixtures for producing transparent plastics, comprising a) a prepolymer, produced from the compounds of formulae (I) and (II), wherein Rindependently represents hydrogen or a methyl group, Rindependently 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 greater or equal 0, with m+1>0, and compounds of formula (III), alkyldithiols or polythiols, preferably HS—R—SH (III), wherein Ris equal or different from Rand can have the meaning indicated in R, and b) at least one radically polymerizable monomer (A) having at least two methacrylate groups and c) aromatic vinyl compounds, such as styrene and d) optionally a radically polymerizable monomer having at least two terminal olefinic groups that have different reactivity, and/or e) optionally at least one monomer (B) from the group of methacrylates, preferably 2-hydroxyethylmethacrylate.
