| Abstract: | The kinetics of polymerization was studied by thermokinectics, based on the conduction type automatic calorimeter (Model RD- I ) , we devised the reactor. The kinetic parameters of curing reaction (apparent activation energies, the rate constant of reaction) were studied for the system hydroxy-terminated poly-butadiene (HTPB) and tolyene diisocynate ( TDI ), the results are in agreement with the values which were determited by TBA,infrared spectrograph and the visco-metric method. |
