The new synthetic routes of a variety of thermally stable polymers were extensively studied. The technical term called “Cyclopolycondensation reaction” was proposed, which involves the formation of heterocyclic ring system in polyaddition and polycondensation reactions. A variety of new heterocyclic polymers such as polyquinazolones, polybenzoxazinones, polyquinazolinediones and ladder polymers were prepared. In particular, the new polymerization process using aromatic diaminodicarboxylic acids as monomer components have been studied in detail, and a variety of new high-temperature plastics for industrial use were synthesized and the evaluation in polymer research and development was carried out. As one class of polymerization reactions, the proton-transfer polymerization of polysulfoneamides and aromatic polyamides was investigated by Michael type addition reaction, and the relation between polymer structure and properties was investigated. The physical properties of the polymers such as thermal stabili y of resultant polymers were determined, and the new polymerization process was established for the synthesis of new type of thermally stable polymers.
