## SYNOPSIS Poly(ethy1ene terephthalate) fibers were aminolyzed in n-butylamine vapor and aqueous n-butylamine. Both aminolysis reactions resulted in weight loss, reduction of molecular weight and tensile strength, and some increase in density. After extraction in chloroform, weight loss of the am
The experiments were carried out in excess ethylene glycol (EG) and poly(ethylene terephthalate) (PET) oligomer in the presence of zinc acetate as catalyst at 190ยฐC. It was found that during the glycolysis reaction, the monomer and dimer were contained in the liquid phase. After 2 h of the glycolysi
