| titleOfInvention | Method and apparatus for continuously preparing crosslinked, solution-cast polymer film |
| abstract | A method and system for continuously preparing a crosslinked, solvent-cast film are disclosed. The method includes continuously providing a pressurized stream of polymer solution, continuously combining a fluid stream including a crosslinking agent with the pressurized stream of polymer solution, mixing the combination of polymer solution and fluid stream in-line, continuously applying the resulting mixture to a continuously moving surface, and then evaporating solvent from the mixture to form a polymeric film. The system includes: (i) a continuous polymer solution casting system, including a first pump in fluid communication with a supply of polymer solution, a casting die for continuously depositing polymer solution disposed in proximity to a moving casting surface, and a first conduit providing a flow path for the polymer solution from the pump to the casting die; (ii) a secondary liquid component injection system, including a second reservoir for holding a supply of a secondary liquid component including a crosslinking agent, a variable-speed second pump in fluid communication with the supply of secondary liquid component, a needle valve, and a second conduit providing a flow path for the secondary liquid component from the reservoir, through the second pump, then through the needle valve, and to an outlet; (iii) a conduit junction connecting the outlet of the secondary liquid component injection system to the first conduit of the continuous polymer solution casting system, the junction disposed downstream of the first pump; and (iv) an in-line mixer disposed between the casting die and the conduit junction. |
