[1] (10 pts.) The Gordon-Taylor equation can represent the glass-transition temperature Tg of a two- component system in terms of weight fractions of components: T (copolymer) = wT+kwT w+kw (k = constant) - W (a) Show that = [1 T] = kI kI W (b) Using the following data for the blends of poly(methyl methacrylate):Polymer 1, with poly(epichlorohydrin): Polymer 2, plot vs. T to get k and T2, assuming T = 113C. Weight fraction of 2 Transition temperature, C 0.000 113 0.200 52 0.300 42 0.430 11 0.700 -3 1.000 -19
