Production of porous diene polymer pellets by mechanical drying |
摘要 |
A process for finishing a hydrogenated diene polymer by producing porous pellets from a water slurry of the hydrogenated block copolymer. The process comprises adjusting the water content of the slurry to from 9 to 16 percent by weight, moving the slurry through a mechanical two-stage extruder dryer, drying the slurry at a temperature of 100 to 180° C., and recovering porous copolymer pellets having a moisture content of 0.2 to 3.0 percent by weight. |
