Abstract

In order to apply the click chemical curing system of polybutadiene into the practical process, the non-isothermal differential scanning calorimetry (DSC) method was used to investigate curing reaction kinetics of terminal alkynyl polybutadiene (PTPB)-triazide acetate propane (TAP)-terminal azido polyethylene glycol (APEG) system. The curing temperature and kinetic parameters of this curing system were calculated by the heating rate-temperature extrapolation method, the Kissinger model, the Ozawa model and the Crane model, respectively.The isothermal curing behavior of the curing system was predicted by nth order kinetics model and model free kinetics (MFK). The results indicate that this system has a low curing activity at 60℃ and the curing rate constant is only 3.13×10^-5 min^-1. When the mass fraction of the catalyst (CuCl) is 0.1%, the rate constant is 5.6×10^-3 min^-1, which is two orders of magnitude higher than that of the hydroxyl terminated polybutadiene-toluene diisocyanate (HTPB-TDI) curing system. The MFK prediction result is closer to the measured result.In addition, when the mass fraction of CuCl is 0.1%, the curing system requires only 10.4h to complete curing at 30℃.
