PROCESS FOR PRODUCING OXYMETHYLENE POLYMERS

摘要

PURPOSE: A manufacturing method of oxymethylene polymer is provided to simply manufacture high stable oxymethylene polymer at low energy cost. CONSTITUTION: A manufacturing method of oxymethylene polymer comprises the following steps: polymerizing non-uniform mixture which includes monomer; increasing temperature during the polymerization in order to be enough for the homogeneous polymer molten product to be existed at the end of the polymerization; inactivating activation polymer chain by supplying inactivator inside the polymer and monomer mixture; hydrolyzing the deactivated homogeneous polymer mixture; and precipitating the oxymethylene polymer hydrolyzed from the outcome.
