Described is an improved process for the preparation of fully methylolated, substantially fully etherified, and substantially monomeric tetramethoxymethlglycoluril useful as a crosslinking agent for powder coatings. The improved process adds after the conventional steps of methylolation and etherification the new steps of acidic distillation followed by an additional etherification.
