Low temperature relaxation processes and electric properties of copoly(ester-ether) elastomer
Electric properties (e', e'' and tg d) of block copoly(ester-ether) elastomer containing 50 wt. % of ollgo(butylene tere- phthalate) blocks have been determined at temperature range 110—190 K (-163 — +17°C). The method of thermally stimulated polarization and depolarization has also been applied. Two relaxation processes, a and b, are described as the glass transition and the process connected with local movements of amorphous domains of flexible segments, respectively.
