DISPERSION CONTAINING FLAME-RESISTANT POLYMER, FLAME-RESISTANT FIBER, AND CARBON FIBER |
摘要 |
<p>An object of the present invention is to provide a dispersion containing a flame-resistant polymer, which can improve shaping stability of the flame-resistant polymer during ejection from a die orifice, and physical stability of a shaped product in a washing step. The dispersion containing a flame-resistant polymer is a dispersion in which a flame-resistant polymer is dispersed in an organic solvent, an in-water tensile strength thereof per unit cross-sectional area is 1.0 MPa or more and 6.5 MPa or less, the flame-resistant polymer can be preferably obtained by heat-treating an acrylonitrile polymer in the presence of at least one kind of acid, acid anhydride or acid chloride in an organic solvent, and a suitable organic solvent is a polar organic solvent.</p> |
