## Abstract ^31^P chemical shift‐structure correlations were established from methyl and ethyl esters of simple phosphonocarboxylic acids. The influence of solvent, acidity, function and neighbourhood of phosphorus was studied. The correlations could be extended and led to the identification of est
## Abstract Two series of hydrogels of poly[(acrylic acid)‐__co__‐(itaconic acid)] have been prepared by copolymerization in solution using tetrafunctional __N__,__N′__‐methylenebisacrylamide (NMBA) as cross‐linker. The resulting polymer was swollen in water at 298 K to yield homogenous transparent
