Trioxane, radiation-induced polymerization

It is important to recognize that in such cases the rate law of polymerization as obtained by determination of the polymer yield reflects the growth of morphological entities rather then the formation of molecular intermediates and may be determined by the rate of nucleation and by the rate of diffusion of the monomer molecules across the interphase between monomer and polymer lattice. This is well established in the somewhat related case of radiation-induced polymerization of crystalline trioxane (27, 28). [Pg.274]

Crystalline polymers were obtained by the radiation-induced polymerization of various cyclic compounds in the solid state " . Especially the cyclic oligomers of formaldehyde (CHjO), i.e., trioxane (TOX) (n = 3), tetroxocane (TeOX) (n = 4), pentoxaiK (P OX) (n = 5), and hexoxane (HeOX) (n = 6), easily produce polyfoxy-methylene (POM) by radiation-induced polymerization in the solid state...

The polymerization of trioxane in the crystalline state is a well-known example of radiation-induced solid-state polymerization In the polymerization of crystalline monomers, the topotactical conditions are very important and polymerization is possible only for a very few monomers. The situation is completely different for... [Pg.79]
