Process for the devolatilization of polymer solutions. |
摘要 |
<p>a) feeding the solution via inlet 1 to a zone of indirect heat exchange (21), in which the ratio of the surface used for the heat exchange to the flow of the solution is above 80 m<2>/m<3>/h; b) passing the solution through each of the channels (14) at a speed of less than 0.5 mm/second; c) keeping the polymer solution in each channel for about 120 to 200 seconds and d) separating the volatile components from the devolatilized polymer solution. i</p> |
