a
The degree of polymerization (DP) is the number of monomeric units in the polymer.
b
Determined by SEC in HFIP relative to PMMA standards.
c
Determined by 1H NMR in D2O or DMSO-d6.
d
The number average molecular weight.
e
The dispersity value (Đ) corresponds to the distribution of distinct molecular masses in a batch of polymers.
f
Hydrodynamic diameter (Dh) of a polymer.
g
Determined by dynamic laser light scattering at 173° in 10 mM NaCl solution. Values represent mean ± standard of mean (SEM) from n = 3.
h
Determined by SEC in HFIP relative to PMMA and pSar standards; nd = not determined.
