Abstract

PURPOSE: To prepare polyoxymethylene having high polymerization degree and good thermal stability, by polymerizing formaldehyde using a specific aluminum compound as a catalyst, and heating the polymer thus obtained in the presence of a peroxide compound, etc.
CONSTITUTION: The objective polymer is prepared by (1) polymerizing formaldehyde in the presence of a catalyst prepared by reacting (A) an Al compound of formula (R1 is alkyl or alkoxy; R2 and R3 are alkyl alkoxy, or halogen) with (B) a compound having O or N as a donor and capable of forming coordinate bonds (e.g. salicylic acid) or contacting the reaction product with (C) a phosphoruscontaining compound (e.g. triphenyl phosphite) or an amine (e.g. ethylene-diamine), and (2) heating the resulting polyoxymethylene in the presence of pref. 10-8W 10-5mol, per 1g. of the polyoxymethylene, of (D) a peroxide compound or a Lewis acid.
