Endo-dicyclopentadiene (endo-DCPD) can be polymerized into poly- dicyclopentadiene (pDCPD) with high modulus, excellent impact resistance, and corrosion resistance via ring-opening metathesis polymerization (ROMP). In this study, the cure kinetics of endo-DCPD, activated by recrystallized 1st and 2nd generation Grubbs' catalysts, were investigated by dynamic differential scanning calorimetry (DSC). The experimental DSC data were analyzed to evaluate kinetic parameters using model-fitting method and model-free isoconversional method. Furthermore, the variation of the activation energy (E) and pre-exponential factor (A) values vs. fractional conversion was established in the model-free isoconversional method from which the reaction mechanisms were discussed. |
