Ring-opening polymerization and plasticization of poly(L-lactic)acid by adding of glycerol-dioleate

Abstract Poly-L-lactic acid (PLLA) has been produced by ring-opening polymerization method. During the processes different temperatures and process times have applied to reach an optimum setup that was used produce sample. The sample measured Fourier-transform infrared spectroscopy (FTIR), gel permeation chromatography (GPC) differential scanning calorimetry (DSC) methods identify structure, molar mass define glass transition of product obtain general information about physical chemical properties material. Based on results measures, material’s crystallinity also investigated. plasticization PLLA experiments, previously material (PLLA synthesized polycondensation) plasticised adding glycerol-dioleate. plasticized FTIR, GPC DSC check basic parameters According measurements were found, this approach, temperature reduced 7 °C indicated glycerol-dioleate might act as a plasticizer for without any deviation in structure
