| titleOfInvention | Rotating disc evapo-extrusion process and apparatus therefor |
| abstract | A process for removing volatile components from a thermoplastic polymer composition which process comprises applying to the composition a pressure sufficient to maintain the composition in a substantially liquid state and all or a part of the heat necessary for evaporating the volatile components to the composition, supplying the heated composition under pressure to a machine, having a rotor 8 and a stator 2 face to face and substantially parallel to define a space 6 therebetween, the composition being supplied to the space through an inlet 5 passing through the stator and arranged to deliver the composition onto the face 7 of the rotor 8, whilst maintaining the pressure in the space 6 at from 5 Torr to 1,500 Torr, rotating the rotor 8 to thereby separate a majority of the volatile components and transfer the polymer composition toward the central area of the face 7 of rotor 8 by hydrodynamic pressure and removing the polymer composition from an outlet 14 which is provided at the central part of the face of stator 2. n The method is particularly useful for the removal of the volatile components from polymer compositions having a high content of volatile components as, for example from 25 to 99.9% by weight, particularly methyl methacrylate polymer compositions for the production of molding materials or extrusion plates which contain 60% by weight or more of methyl methacrylate monomer. |
