Abstract
AbstractNovel diblock and dihydrophilic ionic–nonionic copolymers, having phosphonic and carboxylic functions at the same carbon atom in the repeating units of the ionic block, were prepared. The addition of 2‐diethylphosphono‐ethyl acrylate (PC) to hydroxyl groups of the polyglycidol block of the poly(ethylene glycol)‐b‐polyglycidol block copolymer was followed by the dealkylation of phosphonic acid esters and the hydrolysis of carboxylic acid esters. The polymer was characterized by 1H, 13C, and 31P NMR. The kinetics of the PC addition and the hydrolysis of the ethyl carboxylate function were also studied, and a simple bimolecular second‐order reaction was established. © 2003 Wiley Periodicals, Inc.
