The following copolymers based on aliphatic sebacic acid were synthesized through a vacuum-melt polycondensation process:poly(sebacic acid)-b-poly(isophthalic acid)(PSA-PIPH).poly (sebacic acid) -b- (tartaric acid) (PSA-PTTA). poly (sebacic acid) -b-poly (ethylene glycol)(PSA-PEG). copolymers of PSA and copolyether (M1= 1500) of epoxy ethane and (tetrahydrofuran)(PSA-PEG/THF). All these copolymers were characterized by means of 1H or 13C NMR. IR spectrometry. differential scanning calorimetry (DSC). Intrinsic viscosity and melting points were measured to estimate the molecular weights of polymers. DSC measurements indicated that PSA-PEG. PSA-PEG/THF have much lower crystallinity. On the other hand,PSA-PIPH and PSA-PTTA exhibit better film or fibre-forming properties than PSA.
