Poly(ethylene terephthalate) Preforms and Bottles

A study was conducted to investigate the poor mechanical strength of poly(ethylene terephthalate) bottle bases. Small-scale X-ray scattering (SAXS) and polarized optical microscopy was used to study the molecular morphology of preforms and bottles.本研究旨在探究聚对苯二甲酸乙二酯（poly(ethylene terephthalate)）瓶底的机械强度欠佳问题。研究采用小角X射线散射（small-scale X-ray scattering，SAXS）与偏光显微镜（polarized optical microscopy），对瓶坯与成品瓶的分子形貌进行了分析。
