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