    Study on Dymamic and Effects of Catslytic Polymerization of Wholly Aromatic Liquid Crystslline Polyester

    • 摘要: 研究了五种催化剂在全芳族液晶聚酯合成过程中的催化效应以及对转化率的影响。通过反应动力学数据求得催化反应速率常数、反应活化能,确定催化剂存在下的全芳聚酯多元共缩聚反应符合二级反应规律。在考察催化剂对聚合物热稳定性副作用的基础上,综合确定并择出适合于全芳液晶聚酯合成用的首选催化剂为双组份体系Pb(Ac)2+Sb2O3和Pb3O4十Sb2O3。

       

      Abstract: The effects of catalysts on Polymerisation of wholly aromatic copolyester are studied. The rate constants and activation energy of catalytic polymerization are calculated from reaction kinetic data. It is found that the catalytic polymerhation follows the
