Abstract
High crystalline and high molecular weight poly[(acetoxyethyl)oxymethylene] was prepared from β-acetoxypropionaldehyde with use of triethylaluminum and diethylaluminum chloride at low temperature. It was also established by infrared, NMR, and X-ray analyses that even protonic acid such as sulfuric acid could produce the crystalline, isotactic poly[(acetoxyethyl)oxymethylene] at −78°C. It is suggested that the polar acetoxy group participates in the steric control of polymerization and the mechanism is presumed.
