a

Polymerization conditions: [lactone]/[4] = 100, [lactone] = 1.0 M in toluene, Trxn = 50 °C.

b

Determined by 1H NMR spectroscopy of crude reaction mixture.

c

Determined using gel-permeation chromatography in THF; calibrated with polystyrene standards.

d

Determined by differential scanning calorimetry.

e

nd = not detected.

f

Mn = 34,000 determined by end group analysis.
