Abstract: PURPOSE:To produce a polyoxymethylene by adding a specific compound(s) in the (co)polymerization of trioxane or tetraoxane using a twin-screw mixer type polymerization reactor, thereby allowing the polymerization to be carried out stably for a long period of time. CONSTITUTION:When trioxane or tetraoxane is subjected to homopolymerization or copolymerization with comonomers to produce a polyoxymethylene using a twin-screw mixer type polymerization reactor, one or more compounds selected from the group consisting of esters of 2-40C carboxylic acids, amides of 2-40C carboxylic acids, alkali metal salts of 2-40C carboxylic acids, alkaline earth metal salts of 2-40C carboxylic acids, liquid paraffins, natural paraffins, microcrystalline waxes, polyethylene waxes, and fluorohydrocarbons are supplied. According to this process, the polymerization can be carried out continuously over a long period of time. Since the above additives are generally used to improve the flowability and the release properties of a thermoplastic resin in heat molding, a polymer produced finally is excellent in release properties.

Abstract: PROBLEM TO BE SOLVED: To obtain an oxymethylene copolymer having an excellent balance of color tone, heat stability and mechanical properties. SOLUTION: This method for producing the oxymethylene copolymer is characterized in that, when an oxymethylene copolymer comprising an oxymethylene unit and another oxyalkylene unit is produced by subjecting a mixture of trioxane and a cyclic ether to bulk polymerization in the presence of at least one kind of a boron trifluoride-based polymerization catalyst selected from the group consisting of boron trifluoride, boron trifluoride hydrate and a coordination compound composed of boron trifluoride and an organic compound containing oxygen atom or sulfur atom, the boron trifluoride-based polymerization catalyst is deactivated by adding a specific amine-based compound to the obtained polymer.

Abstract: PROBLEM TO BE SOLVED: To obtain the subject composition excellent in heat stability and moldability and useful for the mechanical parts of automobiles, etc., electric and electronic apparatuses, office machines such as a computer, building pipes, general merchandise, etc., by blending a polyoxymethylene resin with an antioxidant having a specific structure. SOLUTION: The objective composition is obtained by blending (A) 100 pts.wt. of a polyoxymethylene resin with (B) 0.001 to 3 pts.wt. of a compound shown by formula I (R1 and R2 are each an alkyl) and further pref. 0.001 to 3 pts.wt. of a compound shown by formula II (C) and/or a compound shown by formula III (D), and by adding thereto 0.01 to 10 pts.wt. of formaldehyde-trapping agent (e.g. melamine, benzoguanamine, cyanoguanidine). Preferably, the component A serves as a catalyst-deacrivating agent obtained by adding (E) 0.01 to 3 pts.wt. of a hindered amine compound to 100 pts.wt. of a crude polymer resulted from adding a catalyst for polymerization to trioxane and cyclic ether, etc., as a copolymerizable component.
