| 摘要 |
The invention relates to mixtures for producing transparent plastics, which comprise a) a prepolymer, produced from the 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 a number greater or equal 0 with m + n > 0, and the compounds of formula (Ill), alkyl dithiols or polythiols, preferably HS-R3-SH (Ill), wherein R3, which is the same or different from R2, can have the meaning indicated in R2; and b) at least one radically polymerizable monomer (A) having at least two methacrylate groups; and c) aromatic vinyl compounds, such as e.g. 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-hydroxyethyl methacrylate. ® KIPO & WIPO 2007
