Abstract: In this paper, the dielectric spectra of different chain structure of segmented poly(ether-urethane) copolymer have been investigated. All relaxation phenomena were greatly influenced by the molecular weight of the prepolymer. Conditions of the micro-phase separation have been discussed. The apparent activation energies of relaxation processes were determined.
