    Synthesis And Characterization Of Aliphatic-aromatic Copolyesters Pet-pla From Pet Waste And Lactide
    (Oum-El-Bouaghi University, 2016) Ben Gara, M.; Kammoun, W.; Delaite, C.
    Copolyesters containing aliphatic units in the main chain were obtained by reacting Bis(2-hydroxy ethyl terephthalate) (BHET) with Lactide at a high temperature in bulk in presence of tin (II)octoate as the catalyst. Various copolyesters were synthesized by using BHET/Lactide mass ratio ranging from 70/30 to 40/60. Thermal properties were studied by DSC and TGA, and structural characterization was carried out by 1H NMR spectroscopy. These techniques confirm the insertion of lactide units in PET chains. All copolyesters exhibit some block copolymer character.
