Polymers were analyzed using GPC with static light scattering (SLS) and refractive index (RI) detection in their protected peracetylated form prior to deprotection. Chromatogram traces are shown in Figures S1 and S2.
M/C ratio, 1a′–c′ to catalyst 2 ratio; Mtheor, theoretical molecular weight; Mn, number-average molecular weight; Mw, weight-average molecular weight; Đ, dispersity; DP, degree of polymerization.
Two batches were prepared and characterized separately.
