GPC, gel permeation chromatography; Mn, number average molecular weight; Mw, weight average molecular weight.
↵^a Series number according to the data in Table 1.
↵^b The relative amounts (w/w) of fatty acid initiator and polymer as well as the true polymer Mn values were calculated from relative ¹H NMR peaks of either component.
↵^c Mw was estimated by GPC relative to polystyrene standards and is reported in kilodaltons.
↵^d Viscosity at shear rate 0.1 second⁻¹.
↵^e Flow behavior from shear rate 0.1–100 second⁻¹.
