Notes:
Samples of cis-polybutadiene were cross-linked in the presence of decalin at values of φr (the volume fraction of rubber) ranging from 0.25 to 0.50. After the diluent had been removed, a study was made of the force-extension and thermoelastic behavior of the networks. Within experimental error, the ratio of the Mooney-Rivlin constants 2C2/2C1 was found to be zero for networks prepared at low φr (0.25 and 0.30) but started to increase towards the conventional value at higher φr. The quantity fe/f was found to be independent of the ratio 2C2/2C1 and of the extension ratio α; the average value of fe/f was found to be 0.11.
