21	Production of polyacetal copolymer	JP17510699	1999-06-22	JP2000086738A	2000-03-28	ECKARDT PETER; HOFFMOCKEL MICHAEL DR; MUECK KARL-FRIEDRICH; REUSCHEL GERHARD DR; VERMA SATYAJIT; YEARWOOD MICHAEL
PROBLEM TO BE SOLVED: To provide a method for economically and advantageously producing a stable copolymer of 1,3,5-trioxane according to a continuous method. SOLUTION: This method is a continuous method for producing a polyacetal copolymer from 1,3,5-trioxane and a comonomer known for the purpose using a strong protonic acid as an initiator. In the method, the initiator is added in an amount of 0.01-0.6 ppm based on the total amount of the monomers in a finely divided form to a monomer mixture. A crude polymer is then transferred from a polymerization reactor 1 to a mixing unit 6 without a further intermediate step after the polymerization step and a vacuum is applied thereto in the mixing unit 6 or a part between the polymerization reactor 1 and the mixing unit 6 to thereby separate the excessive monomers from the crude polymer. Generally commonly used stabilizers, auxiliaries, fillers, reinforcing materials and/or colorants, as desired, are contained in the polymer in the mixing unit 6. COPYRIGHT: (C)2000,JPO

PROBLEM TO BE SOLVED: To provide a process for preparing a polyacetal copolymer whereby defects in conventional techniques, such as remaining of impurities (e.g. formaldehyde oligomers) or deposit formation in processing, can be avoided. SOLUTION: In the process for the preparation, with simultaneous end group stabilization, of polyacetal copolymers in a homogeneous phase and working up thereof, cyclic formaldehyde oligomers are copolymerized with cyclic acetals in the presence of an initator in a polymn. reactor R and immediately thereafter the initiator is deactiated by addition of basic substances, the unstable chain ends being degraded down to 0.01-1% in the presence of residual monomer, the product loping the majority of the residual monomer which remains and the impurities dissolved in the product being removed by extraction with solvents, and the product being pelletized after drying and stabilization.

PURPOSE: To obtain a uniform high-quality polymer stably and continuously in high yields, by performing the reaction in a polymerizer of a type of a parallel double-shaft agitator mixer each of whose shaft is provided with a number of paddles, installed so that the side of its rear discharge exit may be higher in level to such a degree that the shaft center forms a specified angle with the horizontal level. CONSTITUTION: Paddles 10 having, e.g., an elliptic sectional shape are secured on shafts so that the clearance between the edge of each paddle 10 and the inside surface of a barrel 8 may be equal to or smaller than 2% of the diameter of the circumcircle of paddle 10 to construct a parallel double-shaft agitator mixer type of polymerizer having an L/D (wherein L is the length of the polymerizer and D is its inside diameter) ≤20, and this polymerizer is installed so that the side of its rear discharge exit 2 is higher in level to such a degree that its shaft center may form an angle of inclination θ of 1W10° with the horizontal level. A liquid or the like feed comprising 50W100mol% trioxane and 50W0mol% other monomers is fed through a feed inlet 1 to the polymerizer, a catalyst such as a boron trifluoride/dibutyl etherate cyclohexane solution is added thereto through a catalyst feed inlet 4 and the reaction is performed while the vessel is heated by means of a jacket 6. The product is sent to the right and is withdrawn from the product discharge exit 2. COPYRIGHT: (C)1986,JPO&Japio

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

Polyoxymethylene polymer compositions are disclosed that contain an impact modifier. In accordance with the present disclosure, the impact modifier is attached to the polyoxymethylene polymer and comprises a thermoplastic elastomer containing carbonate groups, such as polycarbonate groups. In one embodiment, a coupling agent bonds the impact modifier to the polyoxymethylene polymer. Incorporation of an impact modifier containing carbonate groups has been found to produce articles having good impact resistance properties while also preserving the permeability of the material. The polymer composition is well suited to producing containment devices, especially fuel tanks.

The present invention is an improved method for stabilising acetal copolymers by hydrolising the copolymer product in a low energy reaction process wherein undesirable side products are continuously and efficiently removed by melting and extruding the unhydrolysed oxymethylene copolymer into a hydrolysis reaction zone in which the necessary reactants are intimately contacted with the copolymer, preferably by means of flow division and rearrangement mixing technique. Subsequently, the hydrolysed copolymer product is devolatilised to remove the unwanted side products by passing it through a devolatilisation zone preferably having more than one devolatilisation port and a vacuum source from which negative pressure is available for application to the devolatilisation ports so that the undesired products may be effectively removed.
