摘要
用解偏振光强法 (DLI)和粘度法研究了 PET/Al2 O3体系从熔融态等温结晶的动力学过程及分子链的结构 .结果表明 ,无机成核剂 Al2 O3对 PET的合成过程具有一定的催化作用 ,并使反应产物 PET的分子链结构发生变化 ,从而影响了
The isothermal crystallization kinetics and the structure of chains of PET/Al\-2O\-3 were studied by depolarized light intensity (DLI) and viscosity. It is shown that Al\-2O\-3 had certain catalytic action for preparation of PET and resulted in some difference of polymer chains' structure and crystallization kinetics between PET and PET/Al\-2O\-3.
