FIELD: chemistry.
SUBSTANCE: invention relates to a method of producing completely para-substituted aromatic polyamide particles for use as filler, which comprises the following steps: a) adding an aramide polymer solution to a water-based coagulation liquid to obtain a hydrogen-containing moulded product and b) crushing the frozen non-dried or partially dried moulded product, having water content from 10 to 99 wt %.
EFFECT: method enables simple and efficient production of small aromatic polyamide particles which cannot be obtained through traditional grinding methods.
