Continuous manufacturing method of polyacetal resin |
| abstract |
The present invention relates to a process for continuously and stably producing a polyacetal resin containing a copolymer of mainly 1,3-dioxolane and trioxane in the presence of a catalyst in high yield for a long time industrially. When 1,3-dioxolane and boron trifluoride and / or boron trifluoride coordination compound are mixed and the obtained mixture is mixed with trioxane and bulk polymerized in a polymerization reactor to continuously prepare a polyacetal resin, 1, Contacting them while keeping the feed direction of 3-dioxolane equal to that of the boron trifluoride and / or boron trifluoride coordination compound, and mixing for 0.1 to 30 seconds while the linear velocity of the mixed stream is 0.1 m / sec or more. The mixture is then mixed with trioxane. |
