FIELD: chemistry.
SUBSTANCE: invention relates to production of fine-grained polyarylene ether ketone used for application on metallic and ceramic articles and producing composite materials. Fine-grained polyarylene ether ketone is obtained by grinding porous polyarylene ether ketone whose BET surface is greater than 4 m2/g. The porous polyarylene ether ketone is obtained during spontaneous setting of polyarylene ether ketone solution in high boiling point organic solvent, for example diphenyl sulphone.
EFFECT: method lowers the cost of grinding and increases output of the powder.
