Abstract:
1. A process for the preparation of polymers of the formula (I) in which Ar is Ar Ar in which Y are identical or different and are CH or N; Aryl is an aryl group having 4 to 14 carbon atoms; R R A q is 0, 1 or 2; p is 1, 2, 3, 4 or 5; A n is from 5 to 50,000; which comprises the steps of a) reacting at least one monomer of the formula (II) in which X is a leaving group, and R P represents para in respect of the two methylene radicals —CH(A in which Ar, A which is dissolved in an alcohol as a solvent, with a base, to give the compound of the formula (III) in which Ar, A 1 , A 2 , R 5 and n are as defined above, b) warming of the compound of the formula (III) with formation of a polymeric compound of the formula (I), which comprises employing a secondary or tertiary alcohol having at least 4 carbon atoms as the alcohol in step a).
