| 摘要 |
The aromatic polyamide pulp is produced by (a) introducing an inorganic salt i.e. CaCl2, LiCl, NaCl, KCl and/or KBr to an amide and/or an urea organic solvent to make a polymeric solvent, (b) dissolving aromatic diamine in the polymeric solvent to make an aromatic diamine soln., (c) introducing aromatic diacid chloride to the soln. to produce a first polymer soln., (d) adding a ternary amine solvent to the soln., (e) introducing residual aromatic diacid chloride to the soln. to make a second polymer soln., (f) continuously protruding the second soln. (g) maturing the protruded soln., at 25-100≦̸C for 0.5-5 hr, and (g) grinding and drying the matured polymer and a solidifying liquor in the pulping device.
