Abstract

PURPOSE:To prepare a high-MW oxymethylene copolymer excellent in heat resistance, etc., in a short time, by preliminarily polymerizing 1,3-dioxolane in the presence of a boron trifluoride polymn. catalyst and bringing the preliminary polymer into contact with trioxane. CONSTITUTION:Preparation is made of a polymn. catalyst selected from coordination compds. of boron trifluoride hydrate and boron trifluoride with an org. compd. contg. an oxygen or sulfur atom. (e.g., boron trifluoride-diethyl ether complex). 1,3-Dioxolane is preliminarily polymerized in the presence of the above-mentioned catalyst to prepare an active poly(oxymethylene/oxyethylene) copolymer (in the form of a soln.) having a number-average MW of 150-20,000, which is then brought into contact with trioxane to prepare an oxymethylene copolymer. This copolymer is suitably used to produce parts of mechanical structures, electrical and electronic components, etc.
