Polyimide, polyisoindoloquinazoline dione, polyoxazine dione and polyquinazoline dione precursor stages and the manufacture

摘要

The present invention relates to oligomeric and/or polymeric radiation- reactive precursor stages of polyimides, polyisoindoloquinazoline diones, polyoxazine diones and polyquinazoline diones as well as to a method for the preparation of these radiation- reactive precursor stages. The invention provides addition products of olefinically unsaturated monoepoxides on carboxyl group-containing polyaddition products of aromatic and/or heterocyclic tetracarboxylic- acid dianhydrides and diamino compounds or diamino compounds with at least one ortho-position amido group, or on carboxyl group- containing polyaddition products of aromatic and/or heterocyclic dihdyroxy dicarboxylic acids or corresponding diaminodicarboxylic acids and diisocyanates. The radiation- reactive precursor stages according to the invention are suitable, for example, for the manufacture of highly heat- resistant relief structures.
