Abstract
PURPOSE: The polymerization of formaldehyde is conducted in the presence of an adduct of an alkylene oxide to a polyhydric alcohol to produce the titled polymer suitably used as an engineering plastic, because of its giving of desired molecular weight, high flowability and good processability.
CONSTITUTION: An alkylene oxide of 3 or more carbon atoms other than propylene oxide such as butylene oxide are added to a polyhydric alcohol bearing 3 or more alcoholic hydroxyls in one molecule such as glycerol. The product is used as a molecular weight modifier to be dissolved in an organic solvent such as n-hexane together with an anionic polymerization initiator such as dioctyltin dilaurate and anhydrous formaldehyde is introduced into this system by the blowing method to effect the polymerization. After separated, the resultant polymer is esterified to stabilize the molecular chain terminals to give the objective polyoxymethylene.
