Influence of the reticulation structure on the coefficiency of Flory interaction in polybutadiene/toluene system
Samples of cured medium cis polybutadiene compound, formulated with sulphur and accelerator and vulcanized at 433 K, were prepared at different cure times in order to obtain different network structures. Uniaxial stress strain tests were performed at room temperature and analyzed in the frame of the...
