다국어 초록 (Multilingual Abstract)

Poly(1,4-butanediol dilactate succinate)and poly (1,4-butanediol dilactate 2-acetoxy succinate) were prepared by the polycondensation of 1,4-butanediol dilactate with succinic anhydride and 2- acetoxy succinic acid. 1,4-Butanediol dilactate was synthesized from L-lactic acid in the presence of 1,4-butanediol as a difunctional initiator. 2-Acetoxy succinic acid was synthesized from L-malic acid by protecting hydroxyl group using acetic anhydride. The monomers and polymers were identified by ^1h-NMR spectrometer and FT-IR spectrophotometer. The molecular weights and molecular weight distributions of synthetic polymers were measured by gel permeation chromatography. The glass transition temperatures and thermal decomposition temperatures of the polymers were measured by differential scanning calorimetry and thermogravimetry, respectively.
