<p>A process for producing polyoxymethylene by using a reactor wherein trioxane alone or a mixture thereof with a compound which can react with trioxane is fed through a feed port and the formed powdery polyoxymethylene is continuously recovered through a discharge port equipped with a weir. The weir serves to prolong the residence of the reactants in the reactor to thereby improve monomer conversion.</p> |
