Abstract
Dynamics of a trace amount of cis-polyisoprene (PI) dissolved in semidilute polybutadiene (PB)/n-heptane (Hep) solutions as a probe was examined through dielectric normal mode relaxation studies and compared with the results of semidilute PI/Hep solutions. In PI/Hep solutions, the dielectric normal mode relaxation time of PI conforms well to the Muthukumar-Freed theory. It was found that τ of PI internary PI/PB/heptane solutions was expressed by the scaling form τ/τ 0 ≃ G(C PB [η] PI , C PB [η] PB . In the ternary solutions, the dynamics of the guest PI chains in PB solution changes from Zimm-like behavior at infinite dilution to Rouse-like and reptation mechanisms with increasing C PB [η] PI
