Preparation and hydrolysis of poly(2-benzoyloxyethyl vinyl ether) with a narrow molecular weight distribution

Article abstract of DOI:10.1248/cpb.46.555

2-Benzoyloxyethy vinyl ether (BOEVE) was cationically polymerized with the hydrogen iodide/zinc iodide (HI/Znl₂) initiating system in toluene at - 15°C to form a narrow molecular weight distribution (MWD). The poly(BOEVE) obtained had a narrow MWD (M(w)/M(n)<1.2, M(w): weight-average molecular weight, M(n): number-average molecular weight). The M(n) of the poly(BOEVE) increased directly in proportion to the BOEVE conversion and to the reciprocal of the initial HI concentration, that is, the reaction was found to be a living polymerization. The hydrolysis rate of the polymer in the alkaline dioxane-water system decreased with increase in the M(n) of the polymer.
