Versuchsvorschrift

In a further embodiment (the post addition method), an aqueous solution of dimethyloldimethylhydantoin, monomethyloldimethylhydantoin, and dimethylhydantoin is produced by admixing (a) from about 80 to about 90% by weight of an aqueous solution of methylolated dimethylhydantoins having greater than 0.1% by weight of free formaldehyde with (b) about 20 to about 10% by weight of dimethylhydantoin based upon 100% by weight of aqueous solution of methylolated dimethylhydantoins and dimethylhydantoin combined.
