Methods for the purification of sugar solutions using hydrolyzed polyacrylamides as flocculants are herein described. The hydrolyzed polyacrylamides are prepared from emulsion or microemulson polymerization of acrylamide monomer, and subsequently hydrolyzed to a degree of hydrolysis of about 10 to about 50 mole %. The hydrolyzed polyacrylamides have a molecular weight of at least about 10,000,000.

L'invention porte sur des procédés de purification de solutions de sucre à l'aide de polyacrylamides hydrolysées servant de floculants préparées à partir d'émulsions ou microémulsions d'un monomère d'acrylamide polymérisées puis hydrolysées jusqu'à un degré d'hydrolyse d'environ 10 à environ 50 moles %. Lesdits polyacrylamides ont un poids moléculaire d'au moins environ 10,000,000.
