Construction of Pilot-scale, multi-purpose Reactor for living anionic polymerization and mass-production of order-made block copolymers |
| 초록 |
We have constructed a high-vacuum reactor system which is a scale-up of traditional break-seal apparatus for large-scale anionic polymerization. The high-vacuum Schlenk line is consist of a 2-port and a 4-port dual manifold which are connected to a LAYBOLT Vacuum System. A standard round-flask reactor body is used and is fitted with volumetric monomer charging cylinders, a buret for initiators charging to facilitate not only simple polymerizations but also blocking and linking reactions with minimal effort. For the glass-equipments attachment, ROTULEX® Joints and ROTOFLO® stopcock are utilized instead of direct glass seals, and of glass breakseals. With this system, we are succesfully producing 500g batches varing in molecualr weight 1~500K with narrow PDI. |
