    Abstract: The invention relates to a powder comprising particles consisting of a composition comprising at least one polyaryletherketone and at least one flexible thermoplastic polymer. The elastic modulus of the flexible thermoplastic polymer is at least two times lower than that of the polyaryletherketone. The polyaryletherketone forms a matrix in which the flexible thermoplastic polymer is dispersed. The powder particles have a volume-weighted particle size distribution with a median diameter d50 of strictly less than 500 μm. The invention also relates to a process for manufacturing the powder and to uses thereof and objects derived therefrom.

    Abstract: The present invention relates to a reinforced thermoplastic powder composition, comprising: at least one polyamide powder with a d50 of less than 100 μm, from 5% to 70% by weight of at least one glass fiber: with a 150 within the range from 50 to 200 μm, with an lmax of less than 450 μm, with a d50 within the range from 4 to 40 μm, with a form factor F: 150/d50 of between 5 and 15, and from 0.05% to 5% of a pulverulent flow agent with a d50 of less than 20 μm; with regard to the total weight of the composition. The present invention relates in particular to the use of said composition in 3D printing processes for manufacturing reinforced three-dimensional objects.

    IPC: C08L71/00

    Abstract: A composition based on poly(ether ether ketone) (PEEK) including poly(ether ketone ketone) (PEKK), wherein the poly(ether ketone ketone) (PEKK) includes a mixture of terephthalic and isophthalic units, the percentage by weight of terephthalic units, with respect to the sum of the terephthalic and isophthalic units, being between 55 and 85%, limits included, and preferably between 55 and 70%, the composition including between 1 and 40%, limits included, preferably between 5 and 40% and more preferably still between 10 and 30% by weight of PEKK, with respect to the total weight of the composition.

    IPC: C08L77/02

    Abstract: The present invention relates to the use of a mixture of at least one semi-crystalline aliphatic polyamide and at least one amorphous polyamide, wherein the at least one semi-crystalline aliphatic polyamide is obtained by polycondensation: of at least one C6 to C18, preferentially C10 to C18, more preferentially C10 to C12 amino acid, or at least one C6 to C18, preferentially C10 to C18, more preferentially C10 to C12 lactam, or at least one C4-C36, preferentially C5-C18, preferentially C5-C12, more preferentially C10-C12 diamine Ca, with at least one C4-C36, preferentially C6-C18, preferentially C6-C12, more preferentially C10-C12 dicarboxylic acid Cb; in order to prepare a semi-crystalline composition, the modulus of which does not vary by more than 25% within the temperature range from 10° C. to 40° C.
