## Abstract Poly(butylene succinate) (PBSu) and two poly(butylene succinateβ__co__βpropylene succinate)s were synthesized via the direct polycondensation reaction. The copolyesters were characterized as having 7.0.and 11.5 mol % propylene succinate (PS) units, respectively, by ^1^H NMR. A different
## Abstract Poly(ethylene succinate) (PES), poly(butylene succinate) (PBS), and PESβrich copolyesters were synthesized using an effective catalyst, titanium tetraisopropoxide. PES was blended with minor amounts of PBS for the comparison. The compositions of the copolyesters and the blends were dete
