The Q-E scheme is used for quantitatively correlating relative monomer reactivities in copolymerization reactions, introduced by Alfrey and Price in 1947 for the purpose of defining an equation for each cross-propagation rate constant ( k 12 or k 21), in a copolymerization reaction in terms of three constants characteristic of P is considered to be a function of the structures of the monomer: P, Q and e.
$$k = P_1 Q_2 exp\left( { - e_1 e_2 } \right)$$
