| titleOfInvention | Production of oxymethylene copolymer |
| abstract | PURPOSE: To obtain a high-MW oxymethylene copolymer inexpensively in high yield within a short time, by premixing a cyclic ether with a polymerization catalyst of a boron trifluoride type, adding the mixture to trioxane and bulk- polymerizing it. n CONSTITUTION: A cyclic ether (A) (e.g., propylene oxide or 1,3-dioxolane) is well premixed with a polymerization catalyst (B) selected from among boron trifluoride (hydrate) and a coordination compound of boron trifluoride with an oxygen or sulfur-containing organic compound (e.g., boron trifluoride diethyl etherate). The obtained mixture is added to trioxane, which is bulk-polymerized to give an oxymethylene copolymer. Since the polymerization catalyst can be activated by the cyclic ether, the polymerization time can be shortened and the polymer yield can be improved. n COPYRIGHT: (C)1988,JPO&Japio |
