Abstract: The numerical method was applied to correct the experimental thermal conductivity and spe-cific heat of poly(methyl methacrylate) measured via quasi-steady state plate method. In the correction. the step-by-step method was used.The calculation was ended until the temperature difference and tem perature rise speed rate of the calculated curves match the relative data of the experimental curves. The correction amplitude of the thermal conductivity and the specific heat is 1.7 % and 2.8 %,respective- ly,and the corrected data was in the recommended range of relevant references.
