OSTI ID:4118282
Methods are given for synthesizing improved ionexchange resins containing substituted aminomethyl phosphonate groups and having an amphoteric character. The phosphonate in these resins has the formula ROP(O)OHCR/sub 1/R/ sub 2/NR/sub 3/R/sub 4/, where R is an alkyl or aryl group, roups or hydrogen or comprise a unit of a polymeric chain; R/sub 3/ and R/sub 4/ together with N may form a piperidine or morpholine group. Such resins may be derived from the monomeric dialkyl or diaryl hydrogen phosphonate by reaction with a polymeric material. (D.L.C.)
