Use of Lithium titanyl oxalate Catalyst for polycondensation to provide a product of White Polyester in a process of Forming Reagents catalyzed polycondensation of PolyEster.

摘要

It reveals a method of producing polyester, through the catalysis of polyester reactant, under the witness of a porous catalyst, The improvement features the use of titanium xalato lithium as a catalyst to prevent faster sterilization or conversion. The improved process resulted in a new monopoly of high-quality titanium oxalato catalyst for color polyester and antimony free.
