Abstract:
A process for continuously producing a polyacetal resin, comprising the steps of;(1) feeding 1,3-dioxolane and at least one catalyst selected from the group consisting of boron trifluoride and a coordination compound of boron trifluoride separately in the same direction as each other to bring them into contact, and mix them, with each other to obtain a mixture;(2) allowing the mixture to continue for a period of 0.1 to 30 seconds at a linear velocity of at least 0.1 m/sec, then(3) mixing the obtained mixture with trioxane; and(4) conducting bulk-polymerization in polymerization equipment to obtain a copolymer of 1,3-dioxolane and trioxane.
