IMPROVED PROCESS FOR THE PRODUCTION OF A WATER ABSORBENT RESIN BY POLYMERIZATION OF A SUSPENSION WITH INVERTED PHASE, OF A NON-SATURATED ETHYLENE-SOLUBLE MONOMER, INCLUDING IN IT, A WATER SOLUTION FOR A NON-SATURATED ETHYLENIC Soluble OF POLYMERIZATION OF THE INVERTED PHASE SUSPENSION, IN A FIRST STAGE, IN A HYDROCARBON OIL SOLVENT, IN THE PRESENCE OF A SUPERFICIATIVE AGENT AND / OR A POLYMERIC PROTECTIVE COLLOID, USING OPTIONALLY A INITIATING POLYMERIZATION RADICAL, IN THE PRESENCE OF LINKING AGENT, COOLING THE RESULTING PASTE TO PRECIPITATE THE SUPERFICIATIVE AGENT AND / OR THE POLYMERIC PROTECTION COLLOID, AND ADDING AT LEAST ONCE, A WATER SOLUTION OF A NON-SATURATED ETHYLENE POLYMER, AND CONTAINING THE RADICAL POLYMERICATE , A LIAISON AGENT WITH THE FIRST POLYMERIZATION REACTION SYSTEM, IN ADDITION TO OBTAIN THE REACTION OF POLYMERIZATION OF THE INVERTED PHASE SUSPENSION. |
