Solid-state Polymerization of 1,3,5-Trioxane

TXN undergoes solid-state polymerization by chemical-induced processes as well as by radiation. That TXN may undergo polymerization in the solid state was observed as early as in 1930 U1), but for a long time this observation was not used. In 1954 Mesrobian et al. published the first paper on the radiation-induced polymerization in the solid state (acrylamide polymerization) 1121 and the solid-state polymerization of TXN was rediscovered a few years later 113). Radiation-induced solid-state polymerization of TXN gained importance and it was believed that it could lead 

The understanding of the mechanism of this reaction is important because there is no definite borderline between the solid-state and solution or bulk polymerization of TXN. In all these processes the polymer forms a solid phase from the beginning of polymerization and growth proceeds inside and/or on the surface of the solid particles. Thus, the difference between solid-state and solution processes stems from the different mobility and availability of monomer molecules being incorporated into the crystal lattice in the former and being in a liquid phase in the latter system.
