PROCESS FOR RECYCLING A FORMALDEHYDE SOURCE DURING A POLYMERIZATION PROCESS

摘要

A process for recovering volatile components from an oxymethylene polymer process is disclosed. The volatile components are removed from the process and the formaldehyde collected is converted to a cyclic acetal. The formaldehyde is converted to a cyclic acetal by contacting the formaldehyde with a catalyst in the presence of an aprotic solvent.
