✦ Synopsis

Additional studies have been conducted on the radiation-induced, Solid-state polymerization of trioxane. The out-of-source polymerization rate has been investigated as a function of radiation dose and of temperature and time of polymerization. The empirical relationship of log time a Y (where Y is the polymerization percentage) was found to be satisfactory over wide ranges of conversion, of dose, and of polymerization time. At a given dose, the yield was directly proportional to the RSV1.'a (where RbV is the reduced specific viscosity). Either increasing the dose or decreasing the particle size gave lower RSV values a t the same conversions.
