| Abstract: | Polyesters were synthesized by long-chain diacids and diols using melting condensation reaction. The synthetic products were characterized by fourier transform infrared(FTIR) ,1H NMR and gel permeation chromatog-raphy (GPC). The effects of the ratio between diol and diacid, monomers, catalyst category, catalyst content and vacuuming time on the molecular structure of the synthetic products were also investigated in this paper. |
