Abstract
The invention relates to a solid insoluble carrier which is activated for bonding of nucleophilic groups and to a method of its preparation. The carrier contains active groups --O.CO.O.R, where R is the residue selected from the group comprising nitrophenyl, dinitrophenyl, trichlorophenyl, pentachlorophenyl, N-succinimidyl, N-phthalimidyl, and 8-quinolinyl. Active groups are bonded to polysaccharides, phenol-formaldehyde resins, polyacrylates, or polyacrylamides. The invention further relates to a method for preparation of the polymeric carrier, which consists in treatment of polymers carrying hydroxyl functions and selected from the group comprising polysaccharides, phenol-formaldehyde resins, polyacrylates, and polyacrylamides, with esters of chloroformic acid which contain the above mentioned active groups.
