description An oxymethylene copolymer produced from trioxane, a cyclic ether and/or a cyclic formal in the presence of a cationic polymerization catalyst is contacted with a deactivating agent for the catalyst in the state of gas phase at a temperature of 160 DEG C. or lower to deactivate the cationic polymerization catalyst rapidly and completely without causing degradation of the copolymer produced.
