  • the poly (ethylene-co-isosorbide) terephthalate resin thus obtained has a reduced viscosity of 0.63 dL / g, a Tg of 89.0% and a molar ratio of isosorbide to diols of 9.8 moles. %.
  • the ratio of diethylene glycol units relative to the diols is in turn 2.4 mol%.
  • the poly (ethylene-co-isosorbide) terephthalate resin thus obtained has a reduced viscosity of 0.63 dl / g, a Tg of 89.9 ° and a molar ratio of isosorbide to diols of 8.7 moles. % and a ratio of diethylene glycol units of 2.2 mole% relative to the diols.
  • the cracking test implemented is based on ISO 22088: Determination of stress cracking in a given environment, Part 3: Method of the curved specimen.
  • Thermoplastic polyester PI, PI ', P2, P2', P3 and P3 ' are dried under vacuum at 150' 0 and then injected in the form of test pieces 5A. The test pieces are then placed on the test supports.
  • thermoplastic polyester according to the invention has no crack even after 5 weeks of exposure.
  • thermoplastic polyester P3 has microcracks after 4 weeks and cracks after 5 weeks of exposure.
