Abstract
The synthesis of polyimide foams obtained as a result of heat treatment of lyophilized water-soluble salts of polyamide acids based on dianhydrides of 3,3’,4,4’-diphenyloxide-, 3,3’,4,4’-benzophenonetetracarboxylic acids and 4,4’-diaminodiphenyl ether was carried out. A study of the structure and morphology of foam samples obtained was carried out. The results of evaluating the mechanical properties and thermal stability of the resulting polyimide foams are presented.
