1H-NMR spectra were recorded in solution with a Bruker AM 250 (250 MHz) spectrometer, with the TMS proton signal as an internal standard. The number average molecular weight of the polymers were calculated from the ratio of the OCH2 methylene proton signals (δ = 4.05) and the HOCH2 methylene proton signals (δ = 3.65) in the 1H-NMR spectra. 13C-NMR spectra were recorded at 62.9 MHz on a Bruker AM 250 spectrometer with the solvent carbon signal as an internal standard. Analytical TLC was performed on commercial Merck plates coated with silica gel GF254 (0.25 mm thick). The silica gel for flash chromatography was Merck Kieselgel 60 (230-400 mesh). Size exclusion chromatography was carried out on a Waters chromatograph connected to a Waters 410 differential refractometer. Four 5 μm Waters columns (300 × 7.7 mm) connected in series in order of increasing pore size (100, 1000, 105, and 106 A) were used with THF as solvent.
