摘要: Poly(ethylene terephthalate) waste materials were depolymerized by ethylene glycol (EG), diethylene (DEG), and propylene (PG) in the presence of a novel catalytic system: titanium (IV)-phosphate. The new catalyst was synthesized through reaction TiCl4 with triethyl phosphate (C2H5O)3P(O). It found that de- polymerization poly(ethylene fiber pro- ceeds faster (IV)-phosphate com- pared compounds traditionally used this process like Zn(OOCCH3)2. oligomer distribution glycolysis products studied size-exclusion chromatography. © 2003 Wiley Periodicals, Inc.
