Abstract
The crystal structures of trioxane, tetroxane and pentoxane have been examined with a view to identifying the most probable edge dislocations in their crystals. The results of this examination have been correlated with observed directions of polymer growth in the crystalline monomers. From the results it is suggested that initiation of solid-state polymerization may occur in edge dislocations rather than in the perfect monomer lattice.
