<p>The present invention relates to compounds of the formula (1)
<IMAGE>
in which R<1>, R<2>, R<3>, R<4>, R<5>, R<6>, R<7> and R<8> have the meanings given in the description and the remaining radicals have the following meanings:
X, Y and Z are identical or different divalent radicals -O-, -S-, -N(R<9>)- or -C(R<10>)=C(R<11>)-, with the proviso that at least one of the radicals X, Y and Z is not a radical of the formula -C(R<10>)=C(R<11>)-, and in which
R<9> is a hydrogen atom, a branched or unbranched C1- to C8-alkyl radical or an optionally substituted phenyl radical,
R<10> and R<11> are in each case identical or different radicals which have one of the meanings of R<1>,
R<7> and R<8> are identical or different radicals, namely hydrogen atoms, C1- to C6-alkyl or phenyl radicals,
n, m and o are identical or different integers from 1 to 10.
<??>The invention also relates to a process for the preparation of these compounds, processes for their polymerisation, new polymers which can be prepared in this manner, and the use of the polymers.</p> |
