    • The present invention relates to a process for preparing a highly transparent plastic obtainable by free-radical copolymerization of a mixture containing compounds of the formula (I) and (II) where R1 is independently at each instance hydrogen or a methyl radical, R2 is independently at each instance a linear or branched, aliphatic or cycloaliphatic radical or a substituted or unsubstituted aromatic or heteroaromatic radical and m and n are each independently an integer of not less than 0 subject to the proviso that m+n>0, which is characterized in that it is obtainable from a mixture which contains more than 10 mol %, based on the total amount of the compounds of the formula (I) and (II), of compounds of the formula (II) where m+n=2. The present invention also relates to the mixture of the compounds (I) and (II), to processes for preparing the mixture and to particular uses for the highly transparent plastics.
    • 本发明涉及制备通过含有式(I)和(II)化合物的混合物的自由基共聚获得的高透明塑料的方法,其中R 1各自独立地为氢 或甲基,R 2在每种情况下独立地为直链或支链的脂族或脂环族基团或取代或未取代的芳族或杂芳族基团,m和n各自独立地为不小于 0,条件是m + n> 0,其特征在于,其可以从基于式(I)和(II)的化合物的总量的含量大于10摩尔%的混合物获得, 其中m + n = 2的式(II)化合物。本发明还涉及化合物(I)和(II)的混合物,用于制备混合物的方法和用于高透明塑料的具体用途。
