The Gordon-Taylor equation can represent the glass-transition temperature Tg of a two- component system in terms of weight fractions of components: T₂ (copolymer) = W₁ w₁T+kw (k= constant) gl w₁₂+kw₂ (a) Show that =[T₁₁ -Ṭ¿]²±² = kТ¸ − kТ¸² W₂ (b) Using the following data for the blends of poly(methyl methacrylate):Polymer 1, with poly(epichlorohydrin): Polymer 2, plot o vs. T to get k and Tg2, assuming T₁ = 113°C.
