ABSTRACT:
Novel polymers are provided which carry diazomethylene or hydrazonomethylene groups. Such polymers are of especial use in immobilizing carboxylic acids, such as amino acids, with a view to subsequent chemical transformation of such acids, e.g. peptide synthesis. Alcohols and thiols may also be immobilized using the new polymers. Methods for the preparation of the polymers are provided, starting from a variety of polymer types.
