Characterization of one-pot p(TETA/CBA)-PEG

Sample Mn (kDa)a Mw (kDa)a PDI (Mw/Mn) Degreeb

p(TETA/CBA)-PEG (TCP) 24.5 31 1.27 0.87 4.0
a

Number average molecular weight (Mn), weight average molecular weight (Mw), and polydispersity (Mw/Mn) determined using FPLC.

b

Degree branching was determined by reduction of disulfide bonds with TCEP followed by the protection of free sulfhydryls with NEM and analyzed by MALDI-TOF.

C

NMR was used to estimate the relative wt% PEG by integrating p(TETA/CBA) and p(TETA/CBA/PEG) peak area under the curve (AUC).
