This has an important meaning to the industrial manufacture . dsc , waxd and polarizing microscope with hot stage experiments were performed to describe what led the ssp rate acceleration of pet / mmt . it was shown that montmorillonite acted as a very good nucleating agent in pet crystallization process , which results in the lower crystallinity , more small microlites , and more surfaces of microlites 为研究pet mmt固相缩聚效率提高的原因，通过热台偏光显微镜、 dsc 、 x -射线衍射等手段对样品的结晶进行观察与分析研究，结果表明蒙脱土对pet的结晶有明显的成核作用，使其晶核生成速率迅速提高，晶核数量明显增多，从而使整个结晶过程的时间变短，同时形成了更多结构不完善的微晶体。
