Related Articles

Abstract Poly(ether-ester)s based on poly(ethylene terephthalate)poly(tetramethylene glycol) (PET-PTMG) were synthesized by melt polycondensation. The melting and crystallization behavior PET-PTMG poly(ether-ester) were measured by DSC and polarizing optical microscope. The effect of poly(ether-ester) composition on its melting temperature,crystallization temperature,crystalinity and crystal morphology was discussed. Results showed that the melting temperatures of poly(ether-ester) are well correlated to composition by Baur's equation. Poly(ether-ester) possess a two-phase morphology consisting of crystalline and amorphous regions.
