Abstract
Powdered and crumb rubber are prepared by dispersing in a starch alkoxide paste appropriately sized particles of wet curd from the precipitation of a latex emulsion, and then insolubilizing the paste by treatment with select bivalent cations. The result is a starch adduct encasing the particulate elastomer, thereby preventing agglomeration and congealing upon storage.
