中文摘要	the nonisothermal crystallization behavior of polyethylene oxide (peo) in poly(ethylene terephthalate)poly(ethylene oxide) (petpeo) segmented copolymer and peo homopolymer has been studied by means of differential scanning calorimetry, as well as transmission electron microscope. the kinetics of peo in copolymer and peo homopolymer under nonisothermal crystallization condition has been analyzed by ozawa equation. the results show that ozawa equation only describes the crystallization behavior of peo-6000 homopolymer successfully, but fails to describe the whole crystallization process of peo in copolymer because the secondary crystallization in the later stage could not be neglected. due to the constraint of pet segments imposed on the peo segments, a distinct two stage of crystallization of peo in copolymer has been investigated by using avrami equation modified by jeziorny to deal with the nonisothermal crystallization data. in the case of peo-6000 homopolymer, good linear relation for the whole crystallization process is obtained owing to the secondary crystallization does not occur under our experimental condition.
