Polymerization in the crystalline state. IX. Relation between the velocity of radiation-induced in-source polymerization and post-polymerization

A general relation is derived between the polymerization velocities to be expected for crystalline monomers during irradiation at a polymerization temperature and the post-polymerization observed in samples irradiated at very low temperatures and subsequently warmed outside the irradiation source. For acrylamide, the experimental data are in satisfactory agreement with the theoretical relationship. The possible reasons for a deviation from this relationship are discussed.
