PROCESS FOR PRODUCING ACRYLONITRILE-BASED POLYMER SOLUTION SHEARING DEVICE PROCESS FOR PRODUCING ACRYLONITRILE-BASED FIBER AND PROCESS FOR PRODUCING CARBON FIBER

摘要

Acrylonitrile-based polymer solution capable of uniformly and efficiently dissolving the acrylonitrile-based polymer in a solvent and capable of producing an acrylonitrile-based polymer solution stably, /RTI Polymer and Solvent It is a mixture of a polymer and a solvent. It has a cylinder and a rotor rotating in a cylinder. Shearing device It is fed to a dispersion chamber. The rotor is rotated by the road under the following conditions to apply a shearing force to the mixture by the road. Acrylonitrile-based polymer solution to obtain an acrylonitrile-based polymer solution It is prepared by:W = (W_One-W₂) / M 0.12 (kWh / kg).W_One, W₂, M is defined in the specification. Alternatively, W = 1.60, and heating may not be performed.
