| 摘 要： | 合成了一种基于TiO2/SiO2溶胶的高活性PET缩聚催化剂,用电子探针显微镜(EPMA)和热重分析(TGA)表征了催化剂的组分,结果与理论值符合.X射线光电子能谱(XPS)结果证实,催化剂中加入的己内酰胺与Ti存在配位作用,极大地提高了催化剂的活性.所制备的催化剂催化聚合得到的PET性能远优于用传统锑系催化剂制备的PET材料.

| Abstract: | A novel catalyst for the polycondensation of PET based on TiO2/SiO2 sol was synthesized.The composition of the catalysts was characterized by electron probe micro-analyzer(EPMA) and thermogravimetric analysis(TGA) methods.The results indicate that the composition of the catalysts can be well controlled and match well with theoretical values.X-ray photoelectron spectroscopy(XPS) results reveale that caprolactam added into the catalyst has coordinative effects with Ti and gives the catalyst ultra-high activit... |
