Abstract
A polyarylether of the formula (VIII) ##STR1## wherein wherein Z' is 1-3 optionally substituted rings selected from the group consisting of an aromatic ring, a hetero aromatic ring or an aliphatic ring. A is --R.sub.1 --Z--Y in which R.sub.1 is H, C.sub.1 -C.sub.30 -alkyl or -aralkyl or phenyl, Z is a direct bond or CH.sub.2, S, O or NH, Y is CH.sub.3, OR.sub.3, SR.sub.3, NHR.sub.3, N(R.sub.3).sub.2, COOR.sub.3, COOM, SO.sub.3 R.sub.3 or SO.sub.3 M in which R.sub.3 is C.sub.1 -C.sub.30 alkyl and M is alkali metal, produced from 3,6-dihalogen- or -dintro-1,2,4,5-diimide having an N,N-substituent and which is suitable for use as a monomer for high temperature structural and functional polymers, and a process for producing the same are disclosed.
