Abstract: A powder composition of polyarylene ether ketone ketones allowing an excellent castability/coalescence balance suitable for laser sintering. The present invention concerns a composition comprising between 99.6 and 99.99% by weight of at least one powder of at least one polyarylene ether ketone and 0.01 to 0.4% by weight of a hydrophilic flow agent. This hydrophilic flow agent is characterised by an increase in mass (quantity of water absorbed) of more than 0.5% after 5 days of conditioning at a relative humidity of 95%. This increase in mass of the flow agent is determined by means of a Karl Fischer measurement after desorption of the water by a 5-minute treatment at 170° C. This composition is suitable for laser sintering. In particular, it gives the powder an excellent castability/coalescence balance.
