Abstract Novel phosphonate and phosphonic acid-containing bis (methacrylamide) s were synthesized. The phosphonate-containing monomers (1a and 1b) were synthesized by amidation of 2-(2-chlorocarbonyl-allyloxymethyl)-acryloylchloride with diethyl 2- aminoethylphosphonate and diethyl 1-aminomethylphosphonate. The phosphonic acid- containing monomers (2a and 2b) were synthesized by hydrolysis of 1a and 1b with ...
