HYDROPHILE POLYMER SORBENT Russian patent published in 1996 - IPC

Abstract RU 2057763 C1

FIELD: organic synthesis. SUBSTANCE: hydrophile polymer sorbent represents product of interaction of epoxyalkyl(met)acrylate copolymer with cross-linking monomer and with organic hydroxyl-containing modifying agent, mass ratio of said copolymer and modifying agent being (90.2-98.9):(1.1-9.8) respectively. Common formula of mentioned above copolymer is given in specification. Said cross-linking monomer is chosen of group which contains di-, tri-, tetra(met)acrylates of pentaerytritol or their mixture. Mentioned above modifying agent represents compound being chosen of high polyatomic alcohols, polyvinyl alcohols or dextrans, said compound is activated by epichlorhydrin. EFFECT: improves quality of desired product.
