High molecular weight polyoxymethylene was obtained from trioxane crystal by solid state polymerization with γ-irradiation from Co80 source. The crystal structure of trioxane was accurately determinated. By using the crystal structure model of trioxane
the ring-opening polymerization mechanism of trioxane by γ-irradiation may be fairly well explained. Polyoxymethylene obtained by solid state polymerization of trioxane may have two types of molecular chains with different orientations
one parallel to the C-axis of trioxane
while the other forming an angle of 75°37'with the C-axis.
