Abstract:
A method for producing an aryl main chain polymer having aryl-containing basic N-groups of formula wherein P is a polymer comprising the repeating units: wherein R3 is hydrogen, alkyl or aryl, and the units R1 and/or R2 are linked by at least one group selected from the group consisting of: R7 is an aromatic group containing tertiary basic N, R8 is hydrogen, alkyl or aryl, which optionally contains tertiary basic N, X is hydrogen or an alkyl group, comprising a) reacting a metallized polymer P-Me, wherein Me is Li or Na, with one or more aromatic ketones or aldehydes containing tertiary basic N-groups having the formula to give an intermediate product having the formula: and protonating or etherifying the intermediate with water or an alkyl halide, to give the aryl main chain polymer having aryl-containing basic N-groups.
