Abstract:
The invention pertains to a method for obtaining para-type wholly aromatic polyamide particles, comprising the steps: a) introducing an aramid polymer solution into a water-based coagulating liquid to obtain a hydrous shaped product; and b) subjecting the never-dried or partly-dried shaped product having a water content of 10 to 99% by weight to freeze-grinding. These aramid polymer particles can be used as a filler material.
