| 摘 要： | 应用 DSC、 TGA和 TMA研究了固相聚合 PET树脂的双重熔融行为、热稳定性及瓶坯、包装瓶的结晶性能和膨胀性。结果表明 ,固相聚合 PET树脂在不同升温速度下的双重熔融行为反映出树脂结晶结构的完整性 ,可为确定固相聚合生产的工艺条件提供参考。对具有不同结晶性能和热稳定性的固相聚合 PET树脂 ,其制坯及吹瓶工艺条件应作必要调整。

| Abstract: | The double- melt behavior,thermal stability of soild state condensation polymerization of PET and the crystallization,expansibility of PET bottle have been studied by DSC,TGA and TMA.The results indicatied that the crystalline perfection was reflected from the dou- ble- melt behavior in different heating rate,thatcan give the reference for the solid state con- densation polymerization of PET. |
