Abstract
The radiation-induced bulk polymerization of acrylonitrile at 20°C was studied kinetically. The polymerization proceeded with precipitation of polymer from the liquid monomer and reached a steady state after an initial acceleration period. The dose rate exponent of the rate of polymerization at steady state was about 0.9. On the basis of the kinetic treatment of the polymerization which contained both first-and second-order terminations for the concentration of progagating radical, the rate constant of each elementary reaction was found to be: ki=2.90×10−11, kp=2.40, ktr=1.48×10−4, kt1=6.33×10−4, kt2=2.27×102.
