  • Process for obtaining an elastomer in solid phase starting from its polymer solution
    Patent number: 8252892
    Abstract: A process for obtaining an elastomer in solid phase from its polymer solution which comprises: (a) optionally pre-concentrating the polymer solution coming from the production system by a flash process; (b) subjecting the polymer solution to a concentrating stripping operation by water vapor in a mixing device comprising internal moveable mixing parts which transfer minimal mechanical energy to the solution in the form of friction heat; and (c) subjecting the concentrated polymer phase coming from (b) to devolatilization by mechanical energy and/or vapor flow to remove residual solvent.

  • PROCESS FOR OBTAINING AN ELASTOMER IN SOLID PHASE STARTING FROM ITS POLYMER SOLUTION
    Publication number: 20110269931
    Abstract: 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.
