Where Mn is the number average molecular weight, Mw is the weight average molecular weight, Xn, is number average degree of polymerization, Xw, is weight average degree of polymerization and Đ is the polydispersity index. All reactions were performed with 10 mg of N6P-Br (1 eq.) at RT. All GPCs were reported after washing with MeOH/diethyl ether. Polymer molecular weights were determined using gel permeation chromatography (tetrahydrofuran as the eluent) against polystyrene standards.
