Abstract (en)

[origin: WO9716596A1] A method for preparing wholly aromatic polyamide pulp which comprises conferring an orientation to the polymer just before gelation of the polymer and ageing the gel, wherein the polymerization solvent is used as a heating medium for the ageing, can improve the physical properties of the pulp, such as molecular weight, crystallinity and development of fibril, as well as bring remarkable effects economically including exclusion of the processes for regenerating nitrogen and removing moisture, and low production cost. In addition, there is no danger of explosion of the liquid heating medium.
