Abstract
A shape-retentive compacted article is produced from 1,3-dibromo-5,5-dimethylhydantoin particulate solids by (a) granulating the particulate solids without use of a binder, and (b) pressure compacting granulated 1,3-dibromo-5,5-dimethylhydantoin granules formed in (a) that have a U.S. standard mesh size in the range of about 80 mesh to about 3 mesh, again without use of a binder. So far as is known, never before have 1,3-dibromo-5,5-dimethylhydantoin particulate solids been converted into a compacted form by any method.
