ABSTRACT OF THE DISCLOSURE A process for the production of high molecular weight oxymethylene copolymer in the presence of impurity is provided. The process provides a high molecular weight oxymethylene copoly- mer having a predetermined comonomer content. The process com- prises the steps of determining the optimal catalyst concentra- tion in a first oxymethylene copolymerization system which contains less than approximately 10 p.p.m. impurity; determining the concentration of impurity containing at least one active proton in a second copolymerization system; adjusting the catalyst concentration in the second copolymerization system so that the total concentration of catalyst and impurity in the second copolymerization system is maintained at the optimal concentration of catalyst in the first copolymerization system; and adjusting the concentration of comonomer in the second copolymerization system so as to maintain the predetermined comonomer content in the oxymethylene copolymer product.
