Notizen:
In order to verify precisely the applicability and reasonableness of the time-humidity superposition method to hydrophilic crystalline polymers, stress relaxation measurements were carried out with films of polyvinyl alcohol and nylon 6 by means of a table model Instron Tensile Tester equipped with a special glass cell to control temperature and humidity. In the case of PVA, only the time-humidity superposition is applicable at humidities higher than that at which the transition begins. For nylon 6, on the other hand, time-temperature and time-humidity superposition apply very well in the transition region and fairly well at higher temperatures and humidities. The results obtained by both the superpositions coincide very well, showing the time-humidity superposition is as reasonable as the time-temperature one. The superposed results were also compared with other existing data, and the reasonableness of the time-humidity superposition was confirmed.
