Phonons and heat capacity of polyoxymethylene

Authors


Abstract

Using Wilson's GF matrix method as modified by Higgs for an infinite system, we report normal modes and their dispersion for polyoxymethylene using the Urey-Bradley force field. Heat capacity has been evaluated as a function of temperature from dispersion curves via density-of-states. The results obtained agree well with the experimental data reported in the literature. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2011
