摘　　要：采用平衡法测定了PET在36%乙酸水溶液中的溶解度和亚稳区,采用降温法在乙酸溶液中进行PET晶体生长试验。结果显示PET在乙酸溶液中的溶解度比在水中的大,并有更宽的亚稳区,而且PET晶体在乙酸溶液中更容易生长。虽然晶体生长形态有所变化,但XRD表明其晶相未发生变化。The solubility and the metastable zone of PET in 36% acetic acid solution were determined by dissolution balance method, then the growth test of PET crystal in acetic acid solution was down by slow- cooling method. The result shows the solubility of PET in acetic acid solution is bigger and the metastable zone is wider than these in water, and the crystal growth is easier. The XRD indicates that the crystal phase does not change, though the crystal growth morphology changes to a certain extent.
