| 英文摘要 | The influence of a nucleating agent, a nucleation promoter and their mixture on the crystallization of poly(ethylene terephthalate) (PET) from melt state was studied by different characterization techniques including the measurements of the crystallization temperature in a non-isothermal cooling process, half time in an isothermal crystallization process and the specific surface free energy for nucleus formation during crystallization. The nucleating agent used was a derivative of sodium benzoate while the nucleation promoter was a sort of low molecular weight ester-ether copolymer. It was found that the nucleating agent could promote the nucleation and crystallization of PET, reducing the specific surface free energy for nucleus formation during crystallization. However, the nucleation promoter had little influence on the nucleation and crystallization rate of PET in the high crystallization temperature range. The nucleation promoter may slightly increase the degree of crystallinity of PET, when the mixture of the nucleating agent and the nucleation promoter was used, the crystallization behavior of PET from its melt state was mainly controlled by the nucleating agent. |
