The cyclotrimerization of following aromatic dinitriles with benzothiazole ring were investigated:The weight loss of polymers obtained under optimum conditions at 371℃ (700°F) in air during 200 hours was about 15%. It was superior than ordinary heat-resistant polymers. Its deformation temperature was above 400℃. The formation of 1
3
5-triazine ring by cyclotrimerization of cyano group was verified by infra-red spectro-scopy.
