, where the amplitudes 𝛾 4 " and 𝛾 4 5 (valid below and above the transition temperature, respectively), and the transition temperature 𝑇 , are not universal, i.e., they can depend on the curing percentage. The exponent 𝛼 (the same exponent describing the behavior of isobaric specific heat) and the ratio of amplitudes 𝛾 4 " 𝛾 4
