A PREPARING PROCESS OF LIQUID CATALYST CONTAINING TITANIUM FOR POLYESTER OR COPOLYESTER

摘要

A preparing process of liquid catalyst containing titanium for polyester or copolyester is as follows: reacting tetra n-butyl titanate, ethylene glycol, tetraethyl orthosilicate, and metal cocatalyst in a solvent,removing the small molecule in the reacting system, and then introducing the complexing agent and reacting to obtain the liquid catalyst containing titanium.
