The heat stability and corrosion resistance of vinyl polyester resins can be improved with Tolylene Diisocyanate (TDI) in this study. Results of Tg temperature measured by a temperature deformation meter, reaction kinetics measured by FTIR and viscosimeter, weight variation of resins measured by a immersion test, mechanical properties measured by a tensile tester, morphology measured by scanning electron micoscope show that vinyl polyester resins modified with TDI have good properties and are efficient.
