Calculation of Polarity Parameters of Initiator Radicals

Abstract

This paper describes a method for calculating the intrinsic e parameter of initiator radicals by applying the intrinsic Q-e scheme to the addition reaction between initiator radicals and monomers. Furthermore, DFT calculations show that there is a good relationship between the intrinsic e-value of initiator radicals and their electronegativity and Hammett constant, indicating that the e-value is a suitable parameter to describe the polar effect of initiator radicals.
