Phase behavior of poly(4-trimethylsilylstyrene) (PTMSS) / polyisoprene (PI) and poly(4-tert/-butylstyrene) (P/BS) / PI blends was investigated by optical microscopy and dynamic viscoelasticity. Number-average molecular weights of PTMSS, PtBS and PI were 8.5 × 10³, 1.1 × 10⁴ and 6.5 × 10³, respectively. PTMSS / PI and PtBS / PI blends were homogeneous and looked transparent in a temperature range from room temperature to 240 °C, suggesting that these blends are miscible. Temperature dependence of dynamic loss tangent, tanδ in these blends exhibits single peaks and its peak top temperature T_max monotonically increases with increasing PTMSS or PtBS fraction. This result indicates that miscibility of PtBS with PI is similar to that of PTMSS with PI.
