This copolymer is obtained by mixing the components A-C together with a cation polymerizing catalyst (e.g.: p- nitrobenzenediazonium tetrafluoroborate or the like) under inert atmosphere in dry state.

PURPOSE: To provide the title polymer having a high mol. wt. in an extremely small usage of a catalyst in a high polymerization yield and, in the case of copolymerization, provide a copolymer reduced in the unstable terminal portions thereof, by using a hetero polyacid (acidic salt) as a polymerization catalyst. CONSTITUTION: The objective polymer is provided by polymerizing formaldehyde or a cyclic oligomer thereof or copolymerizing these main monomers with other copolymerizable monomers with a hetero polyacid or an acidic salt thereof (preferably silicomolybdic acid, phosphotungstic acid, etc.) as a polymerization catalyst. The above-mentioned polymerization catalyst is preferably used in an amount of 0.2W50ppm based on the total amount of the monomers to be polymerized. It is further preferable to add ammonia, etc., as a catalyst deactivator to the polymerization-finished reaction system to neutralize and deactivate the polymerization catalyst.

PURPOSE: To eliminate the vaporization loss of a raw material, the deterioration of the polymer by heat, and the clogging of the recovery line due to the waste gas formed in the polymerization, by polymerizing trioxane, etc. in a specific reactor, and by stopping the reaction with a tertiary phosphine compound. CONSTITUTION: (A) Trioxane and/or a cyclic ether and/or a cyclic acetal and (B) boron trifluoride (hydrate) and/or its coordination compound with a compound containing O or S as a catalyst are fed to the feed inlet 14 of the continuous closed agitated mixer having no opening to the air other than the inlet 14 and the product outlet 12, and polymerized. The resulting polymer is mixed with (C) a tertiary phosphine compound of the formula PR 1R 2R 3 (R 1, R 2 and R 3 are 1W18C alkyl or aryl groups) from the inlet 15 to stop the polymerization, and the waste gas formed is discharged from the suction hole 13. Thus, the product is taken out of the opening 12. COPYRIGHT: (C)1980,JPO&Japio
