Abstract : The IR spectra was used to study the processes occurring in polymers based on 1,6-bis(p-oxyphenyl)hexane, 1,8-bis(p-oxyphenyl) octane, 1,10-bis(p-oxyphenyl) decane, and 1,1-bis(p-oxyphenyl) cyclohexane during their hardening and thermal degradation. Polymer specimens were obtained in the form of films on NaC1 plates from a solution in acetone and then were hardened by sequential heating in the temperature interval 70-330 degrees C in a current of nitrogen. The nitrogen significantly reduced the rate of oxidizing processes. (Author)
