aInitial feed ratio of monomers to catalyst. bMn and Mw/Mn values were determined by SEC analyses with equivalent to polystyrene standard. cIsolated yields. dThis sample was prepared by a one-pot living polymerization of M1 and M2 with a reported Pd(II) complex (ClPd(PEt3)2-OH). eThis sample was prepared by a ring-opening polymerization of M2 using mPEG-OH (mPEG-OH; Mn = 1,900 g/mol) as a macroinitiator.
