Abstract: The orientation dynamics of low-mass compounds (LMCs) in cross-linked rubber during uniaxial stretching were studied. Small amounts of LMCs such as 4-cyano-4'-pentylbiphenyl (5CB) and styrene-based tackifier (TF) were added into polybutadiene rubber (BR). The rubber sheets were uniaxially stretched by a tensile machine equipped with an optical system to measure both the retardation and the stress-strain curve simultaneously. It is found that the orientation of LMC molecules does not relax even after the cessation of stretching. The results demonstrate that orientation relaxation of LMC molecules hardly occurs because of the Nematic interaction, i.e., internal orientation correlation. The stress-optical coefficient C_R is enhanced by the addition of 5CB, whereas the TF addition decreases the birefringence. The results demonstrate that both 5CB and TF-molecules are oriented to the stretching direction with BR chains.
