## Abstract Poly(ethylene isophthalate‐__co__‐ethylene terephthalate) (PEIPET) copolymers of various compositions and molecular weights were synthesized by melt polycondensation and characterized in terms of chemical structure and thermal and rheological properties. At room temperature, all copolym
## 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 parts—soluble and insoluble in CHCl~3~—characterized and used as a raw material to synthesize copolyesters. The solubl
## Abstract Poly(ethylene/butylene terephthalate) (EB) copolyesters were synthesized from ethylene glycol (EG), 1,4‐butanediol (BDO), and dimethyl terephthalate with different molar volume ratios. The constitutional units, characterized by ^13^C NMR, revealed a random distribution in the molecular
