Conclusions

  1. 1.

    A discussion is given of the mechanism of initiation of radiational ionic graft polymerization, and the growth of the graft chains in the polymeric matrices.

  2. 2.

    The effect of the solvent on the rate of ionic graft polymerization is largely determined by ion solvation.

  3. 3.

    The graft polymerization rate is a maximum at the principal relaxation transition point (the glass point) of the swollen polymer.

  4. 4.

    Radiational graft polymerization involves both radical and ionic processes. An equation relating the contribution of the ionic process to the polymerization, the dose rate, and the concentration of inhibiting contaminants in the system (H2O) is derived and analyzed.

  5. 5.

    It is shown that the contribution from the ionic process increases with a rise in the dose rate. In the radiational graft copolymerization of styrene with acrylonitrile, the effect of the ionic process becomes appreciable at a dose rate of 103 Gy/sec.
