【摘要】 考察了玻璃化温度与ＰＢＴ／ＰＥＴ共混物组成的关系，讨论了晶相分离及其对相溶性的影响，片晶间非晶部分的相溶性等，表明结晶相分离将导致非晶部分组分比的改变，但不会导致非晶部分的组分相分离，片晶间非结晶部分的ＰＢＴ和ＰＥＴ仍然是相溶的．更多还原

【Abstract】 The relation of the compisition of PBT/PET blends and their glass transitiontemperatures, the effect of crystal phase separation on the compatibility, and the compatibility of the uncrystallized regions between lamella have been studied acconding tothe results of DSC and DMA’ It is shown that the crystal phase separation leads to thechange of composition of the uncrystallized regions, but does not lead to phase separatIOn’’更多还原
