Zusammenfassung: | Polymers containing azo dyestuffs which, as characteristic monomer units, contain radicals of the formulae I, II, III and IV
in which
D denotes the radical of a heterocyclic diazo component,
R and R in each case denote hydrogen, C1-C6-alkyl or optionally substituted C1-C6-alkoxy, or R also denotes C1-C4-alkanoylamino,
R denotes hydrogen, C1-C6-alkyl, C5-C7-cycloalkyl or C3-C4- alkenyl,
R denotes hydrogen, deuterium, methyl, trideuterated methyl or chlorine,
R denotes hydrogen or deuterium,
Y and Y in each case denote optionally substituted C2-C10-alkylene,
W denotes oxygen, imino or C1-C4-alkylimino and
X denotes hydroxyl, optionally substituted C1-C6-alkoxy, phenoxy, amino or C1-C4-mono- or dialkylamino,
where the average molecular weight of the polymer is 1000 to 100,000, their use in non-linear optics and the use of monomeric azo dyestuffs for the preparation of the novel polymers. |
