一步法合成聚酯工艺的研究

Research of One - stage Process Polyester Synthesis

从反应时间、反应温度和物料配比方面考察了一步法合成聚酯的工艺条件,与两步合成方法比较,一步法合成聚酯具有明显的优势,可以缩短反应时间和降低反应温度。

The conditions of one - stage process polyester synthesis from the aspects of reaction time, reaction temperature and reaction substance ratio were investigated, one - stage process polyester synthesis had clear superiority to two - stage process , the reaction time could be shortened and the reaction temperature could be descended.
