Thermally stimulated depolarization of poly(ether block amide) copolymer
Phase segregation in poly(ether block amide) copolymer has been studied by thermally stimulated depolarization (TSD). Well-defined, complex and partial phase segregation were observed depending on the molecular mass of each segment of the copolymer. A new glass transition peak appeared were broadened. Soft-segment component poly(tetramethylene glycol) (PTMG), with a lower molecular mass, was found to be completely amorphous. No additional Maxwell-Wagner-Sillers (MWS) effect peak at the phase boundaries was detected.
