Abstract
Crosslinked macroreticular and gel-type quaternary ammonium acrylamide anion exchange resins which possess a potential for hydrophobic bonding and thereby display a high affinity for slightly ionized or unionized refractory color bodies as well as for the more easily removed color bodies in aqueous sugar solutions are provided.
Claims18
A crosslinked, macroreticular, quaternary ammonium acrylamide resin which comprises the product from the reaction of a compound of the formula RX with a crosslinked, macroreticular tertiary amine, acrylamide precursor resin which comprises a copolymer of 0.1% - 50% by weight of a polyethylenically unsaturated monomer and 50% - 99.9% by weight of a monoethylenically unsaturated aliphatic ester of acrylic acid which has been aminolyzed with a polyamine, said resin comprising units having the chemical formula:
- ##STR9## wherein R is a substituted or unsubstituted hydrocarbyl functional group containing 5 - 22 carbon atoms and X.crclbar. is an anion.
A crosslinked, gel-type, quaternary ammonium acrylamide resin which comprises the product from the reaction of a compound of the formula RX with a crosslinking, gel-type, tertiary amine, acrylamide precursor resin which comprises a copolymer of 0.1% - 50% by weight of a polyethylenically unsaturated monomer and 50% - 99.9% by weight of a monoethylenically unsaturated aliphatic ester of acrylic acid which has been aminolyzed with a polyamine, said resin comprising units having the chemical formula:
- ##STR10## wherein R is a substituted or unsubstituted hydrocarbyl functional group containing 5 - 22 carbon atoms and X.crclbar. is an anion.
