9. 3 and colorimetric analysis (530 nm) indicated the presence of 0.39 mmol of ester/g of polymer, which corresponds to 11% ring substitution.
10. In the presence of 150 mM NaCl plus 10 mM phosphate buffer (pH 7), containing 150 mM p-toluenesulfonate, the increase in volume of the polymer was 50% relative to the dry state of the starting resin.
11. A similar degree of inhibition was found in phosphate-buffered saline (PBS) when the NaCl concentration was increased to 3.8 M; the increase in the volume of the resin due to swelling was 44%.
