Molecular weights of synthesized polymers

Polymer	Average molecular weight (g/mol)
	Theoreticala	Observed
PBLG-Bnz	50,000	46,300b
PBLG-PEG	60,000	50,000c
PBLG-FITC	60,000	43,300b

^aNotes: Calculated by considering the constitutional repeating units according to the initial ratio;

^bCalculated from viscosity measurements;

^cCalculated from ¹H-NMR spectra.

Abbreviations: Bnz, benzylamine; FITC, fluorescein isothiocyanate; PBLG, poly(γ-benzyl-L-glutamate); PEG, polyethylene glycol.
