摘要： PURPOSE: To obtain the titled copolymer having high basic stability and a proper molecular weight in good reproducibility, by adding a cyclic formal to a slurry of oxymethylene homopolymer, distilling partially a solvent away, followed by adding a Lewis acid to it.
CONSTITUTION: Formaldehyde is fed from the pipe 12 to the polymerization tank 2, and an inert organic solvent (e.g., toluene, etc.) containing 10
-7 W10
-3 mol/ polymerization catalyst[e.g., copper bis(acetylacetone), etc.]is added from the pipe 11 to the tank, to give a slurry of a homopolymer. The slurry is fed from the pipe 13 and a cyclic formal (e.g., 1,3,6-trioxocane, etc.) from the pipe 14 respectively to the pretreating tank 4, and preferably ≥20wt% solvent is distilled away from the pipe 15. The remaining slurry is fed from the pipe 16 and a Lewis acid (e.g., boron trifluoride diethyl etherate, etc.) from the pipe 17 respectively to the copolymerization tank 6, so that the homopolymer is reacted with the cyclic formal, to give the copolymer.

摘要： PURPOSE:To obtain economically the title polymer with high-polymerization degree and high thermal stability by polymerization of formaldehyde followed by melting the resulting polymer in the presence of a catalyst prepared by bringing a phosphorous-contg. compound or an amine into contact with a reaction product from an organoaluminum compound and a salicylic acid-based compound. CONSTITUTION:In the first step, a catalyst is prepared by bringing a phosphorous- contg. compound or an amine into contact with, by means of mixing operation, a reaction product from an aluminum compound of formula I (R is alkyl or alkoxy; R and R are each alkyl, alkoxy, or halogen) and a salicylic acid-based compound. Formaldehyde is then polymerized in an inert solvent in the presence of the above catalyst and the resulting polyoxymethylene is subjected to melting for >=5min under reduced pressure or an inert gas atmosphere such as of N2-, Ar-gas.
