PROCESS FOR OBTAINING AN ELASTOMER IN SOLID PHASE STARTING FROM ITS POLYMER SOLUTION

Process for obtaining an elastomer in solid phase starting from its polymer solution comprising: 1. a pre- concentration by means of a flash process of the polymer solution; 2. a first removal phase of the vapour by means of an innovative unitary "concentrated stripping" operation; and 3....

Beschreibung
Zusammenfassung:	Process for obtaining an elastomer in solid phase starting from its polymer solution comprising: 1. a pre- concentration by means of a flash process of the polymer solution; 2. a first removal phase of the vapour by means of an innovative unitary "concentrated stripping" operation; and 3. a final devolatilization of the polymer. L'invention porte sur un procédé pour l'obtention d'un élastomère en phase solide à partir de sa solution de polymère comprenant : 1. une préconcentration au moyen d'un procédé de détente flash de la solution de polymère ; 2. une première phase d'élimination de la vapeur au moyen d'une opération autonome de « stripping concentré » novatrice ; et 3. une extraction des matières volatiles finale du polymère.
