ABSTRACT:
Process for the manufacture of a salt of a poly-alpha-hydroxyacrylic acid, which salt contains monomeric units of the formula: ##STR1## in which R.sub.1 and R.sub.2 independently represent hydrogen or an alkyl group containing from 1 to 3 carbon atoms, and in which M represents the cationic radical resulting from the dissociation of a base, by reacting, with the base, in the presence of water, a solid polylactone derived from the corresponding poly-alpha-hydroxyacrylic acid, in which process the reaction is carried out in a liquid medium containing water and a diluent, the diluent being one which does not dissolve the polylactone and the salt produced and being present in an amount such that the polylactone and salt produced do not dissolve in the medium. In the process, an oxidizing agent is added to the liquid medium.
