Abstract (en)
[origin: CA2913520A1] The invention relates to a method for producing a,ß-unsaturated carboxylic acids or salts thereof, comprising a step in which a metallalactone is reacted in a solvent in the presence of a halide; to a composition that comprises a,ß-unsaturated carboxylic acids or salts thereof and halide ions; and to the use of said composition for the production of superabsorbent materials or as a monomer composition for producing polymers.
