摘要: A series of copolyesters were prepared by the direct melt transesterification poly(trimethylene terephthalate) (PTT) and poly(butylene succinate) (PBS). The sequential structure was analyzed with proton nuclear magnetic resonance spectroscopy, randomness calculated to be approximately 0.8. cocrystallization, thermal behavior, spherulitic morphology investigated. melting points showed a pseudo-eutectic behavior exhibiting isodimorphic cocrystallization. Wide-angle X-ray diffraction indicated that crystallized in PTT crystals when butylene succinate (BS) unit content less than 60% PBS BS greater 70%. mechanical properties greatly influenced sequence lengths aromatic aliphatic units. incorporation units into led faster rate degradation because decrease length increase length. © 2010 Wiley Periodicals, Inc.
