Approximation of the previously estimated excess specific heat C^{excess}/T^{5} of two fluoropolymers, PTFE and PCTFE, is presented using Orthonormal Polynomial Expansion Method (OPEM). The new type of weighting functions in OPEM involves the experimental errors in every point of the studied thermal characteristic. The investigated temperature dependence of the function C^{excess}/T^{5} is described in the whole temperature ranges 0.4\div8 K and 2.5\div7 K respectively for PTFE and PCTFE as well as in two subintervals (0.4\div2) K, (2.5\div8) K for PTFE. Numerical results of the deviations between the given C^{excess}/T^{5} data and their approximating values are given. The usual polynomial coefficients obtained by orthonormal ones in our OPEM approach and the calculated in every point absolute, relative and specific sensitivities of the studied thermal characteristic are proposed too. The approximation parameters of this type thermal characteristic are shown in Figures and Tables.
