Summary In this paper is decribed a new method for determining copolymerization reactivity ratios r by using high resolution gel permation chromatography. The system of monomers is a new one involving a macromer. Separation of each monomer, copolymer and solvent allows calculation of concentration of reactants and products, so as the copolymer molecular weight distribution. Three different methods were used to interprete copolymerization experiments, at various feed compositions, and in function of conversion, in minimizing errors on peak surface area. The conventional methods were used to calculate r and evaluate their accuracies.
