ABSTRACT:
Oligomeric or polymeric radiation-reactive intermediates of polyamides, polyisoindoloquinazolinediones, polyoxazinediones or polyquinazolinediones are prepared by a process in which a carboxyl-containing polyadduct of aromatic and/or heterocyclic tetracarboxylic dianhydrides and diamino compounds, or a carboxyl-containing polyadduct of aromatic and/or heterocyclic dihydroxydicarboxylic acids and diisocyanates, or a carboxyl-containing polyadduct of aromatic and/or heterocyclic diaminodicarboxylic acids and diisocyanates is subjected to an addition reaction with an ethylenically unsaturated monoisocyanate.
The products prepared according to the invention are suitable as structure-forming functional or auxiliary layers in the construction of electronic components.
