Strategies in Improving the Accuracy of Reactivity Ratios Estimation

Recently published experimental data concerning more than ten copolymerization systems were re-analyzed. Newer, more accurate, reactivity ratios were calculated using a non-linear method (PROCOP) which involves all the experimental data including conversion values. The differences between the reactivity ratios provided in the original articles and the recalculated values are discussed in terms of experimental errors, analytical methods, conversion values and solvent effect. The present paper shows what is routine, what needs to be changed and what can be realistically hoped for as far as accuracy in reactivity ratios estimation is concerned.
