Abstract
Linear thermal expansion coefficients is obtained from the measurement of change in specimen length which is due to the force unbalance originated from temperature change at equilibrium creep. Thermal expansion coefficient of the unfilled trans - polyoctenamer (TOR) is larger than that of the filled TOR because the occluded rubber with carbon black or filler does not provide the thermoelastic contraction but volumetric expansion. Deviation in the thermal expansion strain above the reference temperature (35℃) is obtained due to the dissolving of processing oil. Linear thermal expansion coefficients with the creep strains of TOR vulcanizates are three times larger than that of the unfilled NR and SBR.
