Summary

Terephthalate copolyesters of ethylene glycol and propane-1,3-diol of various compositions were prepared by trans-esterification of poly(ethylene terephthalate) (PET) with propane-1,3-diol [PrG(1,3)] . The compositions of the coDolyesters were determined by1H NMR. The melting and crystallization temperatures were measured by differential thermal analysis (DTA). Intrinsic viscosities were measured in orthochlorophenol at 30°C.
