Science of Determining Copolymerization Reactivity Ratios

Abstract

Abstract Copolymerization reactivity ratios were originally measured and tabulated for the purpose of describing and classifying the relative reactivities of various monomers toward various radicals in free-radical copolymerization. A great number of reactivity ratios have now been measured and tabulated for this purpose [1]. Within the last few years, the concept of relative reactivity has been extended to ionic and coordination addition polymerization mechanisms, and r1r2 values in these systems are appearing in the literature.
