Parametric Analysis of Tg vs. Composition Behavior in Poly(4-hydroxystyrene) Blends Using both Evolutionary Fitting and Classical Methods

An evolutive fitting method has been devoted to fit the most usual equations that predict T-g vs. composition behavior of polymer blends. This method has been compared and tested vs. two "more traditional" fitting methods. T-g vs. composition results of poly(4-hydroxystyrene) and its blends with poly(methyl acrylate), poly(ethyl acrylate), and poly(vinyl acetate) have been analyzed in terms of different equations.
