Abstract
Storage-stable, discrete free-flowing flakes of a hydrophilic or water-soluble polymer gel, such flakes comprising a thin adherent film coating of a processing aid powder, are facilely produced by comminuting a larger shaped article of said polymer gel, e.g., a block, sheet, strip or layer thereof, in the presence of said processing aid powder, and said powder being present during comminution in an amount in excess of that required for otherwise complete coating of the flakes which result.
