- 中文摘要:
In this study, sodium benzoate was selected as the nucleating agent to improve the crystallization rate of Poly (Ethylene Terephthalate) (PET). A new polyster, PEAT, which was synthesized from Bis Hydroxy-Ethyl Terephthalate (BHET) and adipic acid, was blended with PET to improve the (crystallization) rate of PET at lower temperatures. The crystallization rate of the PET blends was measured with a DSC and the kinetics of crystallization were studied.
It was found that the range of the crystallization temperatures for the PET/ sodium benzoate blends was wider than that for the PET/ PEAT blends which shifts to a lower temperature region. PEAT showed a pronounced effect on the crystallization rate at lower temperatures, which sodium benzoate effected the crystallization rate within the entire range of crystallization temperatures. - 英文摘要: --
