Abstract
PURPOSE: To prepare a polyoxymethylene having improved thermal stability without treatment of the terminal groups, by polymerizing formaldehyde in the presence of the reaction product of a specific aluminum compound with a compound capable of coordinating, adding a phosphorus-containing compound to the polymer, and melting the mixture.
CONSTITUTION: A polyoxymethylene is prepared by polymerizing (A) formaldehyde at -40W+80°C in the presence of (B) the reaction product of (a) an aluminum compound expressed by the formula (R1 is alkyl or alkoxy; R2 and R3 are alkyl, alkoxy or halogen) with (b) a compound capable of coordinating and having oxygen or nitrogen atoms as donors (e.g. acetylacetone, etc.). A phosphorus-containing compound (e.g. tristearylphosphine, etc.) is added to the polymer and the composition is melted at 200W250°C for ≥5min. to give the desired polymer.
