Abstract: Interphase transfer of a coumarone-indene tackifier between natural rubber (NR) and poly(isobutylene) (PIB) was studied. The laminated sheets composed of NR with the tackifier and PIB with the tackifier were annealed at various temperatures to promote the interphase transfer of the tackifier. After separating the post-annealing sheets, the infrared spectra were measured to evaluate the tackifier content in each rubber sheet. It was found that a large amount of the tackifier resided in PIB after annealing at -20 °C, whereas the tackifier moved to NR at 40 °C. Consequently, the NR sheet exhibited lower glass transition temperature T_g after annealing at -20 °C and higher T_g when annealed at 40 °C. The differential scanning calorimetry measurements revealed that the crystallization of NR was responsible for the tackifier transfer. This phenomenon should be noted of interest because the matrix of their blend shows low T_g at low ambient temperature and high T_g at high temperature when NR is the matrix of the blend.
