Liquid monomer feed pipe for continuous extrusion polymerization |
| abstract |
A feed pipe is provided for introducing highly reactive monomers into a continuous reactor to effect polymerization of such reactive monomers. The feed pipe has concentric tubes forming a central flow channel and an annular flow channel which are sized to insure laminar flow within said tubes. The feed pipe is particularly useful for feeding melts of organic dianhydride and organic diamine into an extrusion reactor for polyetherimide preparation. |
