ABSTRACT:
There are provided cephalosporin and penicillin carboxylic acid derivatives which comprise polymers carrying a plurality of molecules of said acid, the carboxyl groups of which are blocked by attachment to the polymer, principally by forming ester linkages to aliphatic carbon atoms in the polymer. There are also provided methods of immobilizing cephalosporin and penicillin acids on polymers and of carrying out chemical reactions to modify said acids.
