Spherulitic growth rate data for polyoxymethylene have been successfully analyzed with the recently proposed nucleation theory by Hoffman and co‐workers that assumes a coherent nucleation mechanism. Lamellar step heights, which were calculated as a function of the crystallization temperature, were in good agreement with experimental values obtained by Geil who used small angle x‐ray scattering. The surface free energy of the nucleus and the end free energy of the fold surface were calculated to be 10.5 and 26 ergs/cm2, respectively. These reasonable values lend further support to this kinetic analysis.
