Integral and differential binary copolymerization equations

Abstract

Abstract An analytic solution to Skeist's copolymerization equation has been obtained for the case of binary copolymerization. From this solution, a differential copolymer composition equation is also derived. For given values of the reactivity ratios, these equations then permit the convenient calculation of expected binary copolymerization behavior as a function of conversion. Critical conditions leading to incompatible copolymerizations are also discussed.
