摘要： A process for producing a polyacetal copolymer, the process making catalyst deactivation easy and efficient. Trioxane as a major monomer is copolymerized with one or more comonomers that are a cyclic ether and/or cyclic formal having at least one carbon-carbon bond, using a nonvolatile protonic acid as a polymerization catalyst at 100° C. or lower until the conversion reaches 50% and thereafter at a polymerization environment temperature of 115° C. to 140° C. This process includes: a crushing step in which a dry-process crusher is used to obtain a crude polyacetal copolymer crushed to such a degree that when the crude copolymer is screened with a sieve having an opening size of 11.2 mm, 90 parts by weight or more thereof passes therethrough; and a deactivation step in which a basic compound (e) is added to the crude copolymer and the mixture is melt-kneaded to thereby deactivate the polymerization catalyst.

摘要： A high-quality polyacetal copolymer produced by a simple process in an economical manner. The process includes supplying a raw material including trioxane and the like to a reaction device; setting the polymerization environmental temperature to no more than 100° C. until the reaction device conversion rate becomes 0.5, and then carrying out further polymerization; vaporizing and separating unreacted monomers from the reaction mixture at an environmental temperature of at least 115° C. and less than 140° C.; supplying the separated monomers to the raw material supply; and recovering the polyacetal copolymer from the reaction mixture.

摘要： To prepare a thermally very stable polyacetal copolymer containing a very small amount of unstable parts in a high yield according to a simple process wherein an isopolyacid or an acid salt thereof is used as the polymerization catalyst in the copolymerization of trioxane as the principal monomer with a comonomer copolymerizable therewith, and wherein deactivation of the catalyst can be effected simply without fail through contact with a basic gas after polymerization without the necessity for any washing step. In the preparation of a polyacetal copolymer by the copolymerization of trioxane as the principal monomer with a cyclic ether or cyclic formal having at least one carbon--carbon bond as a comonomer, the copolymerization is effected using an isopolyacid or an acid salt thereof as the polymerization catalyst, followed by contact with a basic gas as a deactivator to deactivate the catalyst, and subsequent heat-melting treatment of the resulting crude polymer intact without washing thereof.
