## Abstract Poly(ethylene terephthalate), PET reacted with various glycols in the presence of titanium tetraisopropoxide as a catalyst. The glycolyzed PET was fractionated into two partsβ€”soluble and insoluble in CHCl~3~β€”characterized and used as a raw material to synthesize copolyesters. The solubl
