The degradation behaviour of Kodar [poly(1,4‐cyclohexylene dimethyl‐eneterephthalate)] was investigated in air using thermogravimetry, differential thermal analysis and wide angle X‐ray diffraction studies. The rates of crystallization and degradation were influenced by thermal exposure and polychromatic irradiation (Λ > 290 nm) for different time intervals. The crystallinity changes ( X c %) and activation energies (ΔE) for the systems have been determined.
