Abstract
The thermal transitions, microphase structure, local segmental and conducti vity relaxation of the novel polyurethanes (PUs) based on the poly(tetramet hylene glycol) as soft segments (SSs) and 4,4 ' -diphenylmethane diisocyana te-1,4-butane diol sequences of various length as hard segments (HSs) conta ining ionic groups in SSs are studied by calorimetry, X-ray scattering and dielectric relaxation spectroscopy.
