抄録

In order to examine the activation energy and the temperature coefficient in the indirect vulcanization process in comparison with those in the press vulcanization, measurements were made by means of modulus method on three kinds of mixtures of natural rubbers of which mixing ratio near those in practice. It was known that induction time showed by far larger values in the indirect vulcanization and it was also observed in the press vulcanization under some condition, which indicated that, in modulus method, true equivalent vulcanization time was obtained by subtracting induction time from apparent equivalent vulcanization time. Activation energy and temperature coefficient in the indirect vulcanization were estimated to have almost the same vulues as those in the press vulcanization, though the comparison could not be exactly done because of the essential difference of accuracy which existed between the former and the latter.
