^aWhere M_n is the number average molecular weight, M_w is weight average molecular weight, X_n is number average degree of polymerization and X_w is weight average degree of polymerization. Polymer molecular weights were determined using gel permeation chromatography (tetrahydrofuran as the eluent) against polystyrene standards.
