摘要
总结了PET 固相缩聚反应的原理及其反应动力学,综述了国内外研究PET 固相缩聚动力学模型的进展。指出单纯考虑化学反应或小分子扩散的模型都是不全面的,应该用化学反应过程和物理扩散过程共同控制的模型来描述固相缩聚反应。
The mechanism and kinetics of solid state polycondensation of poly(ethylene terephthalate) were summerized. The worldwide recent studies on the model of solid\|state polycondensation of poly(ethylene terephthalate) were reviewed.It was pointed out that the model of only considering chemical reaction or byproduct diffusion was uncomprehensive. Solid state polycondensation should be described as a diffusion and reaction\|controlling kinetics model.
