Hydrotreating of recycled block copolymer solvent |
| abstract |
A process for the removal of impurities from solvents utilized in a cyclic process for the production of block copolymers is provided which comprises separation of block copolymers from their polymerization solvent, the separated solvent having a stated temperature, and hydrotreatment of the solvent with a heterogeneous hydrogenation catalyst at a weight hour space velocity greater than about two, whereby the undesirable contaminents are reduced, and recycling the hydrotreated solvent to the polymerization reactor. |
