Abstract: The present invention relates to (co)polyamides comprising at least 85 mole % (mol. %) of recurring units (RPA) of formula (I): (I); the present invention also relates to polymer compositions comprising such (co)polyamides, as well as articles comprising the same and methods of using said articles in high temperature applications requiring sufficient swelling or deformation upon exposure to moisture, such as for example oil and gas extraction processes (e.g. fracturing balls), or as support materials used to print three-dimensional (3D) parts.

Abstract: The present invention relates to a of amide copolymer produced from a carboxy-piperidine, preferably 4-piperidinecar-boxylic acid and an aminoacid or lactam, preferably 4-aminomethyl-benzoic acid, to a process for its manufacture and to the use thereof for the manufacture of thermoplastic composites, and articles manufactured via injection molding, extrusion and through additive manufacturing technologies.

Abstract: The present invention relates to a novel polyamide polymer, to a process for its manufacture and to the use thereof for the manufacture of thermoplastic composites, and articles manufactured via injection molding, extrusion and through additive manufacturing technologies.

Abstract: The present disclosure relates to a method for manufacturing a three-dimensional (3D) object with an additive manufacturing system, comprising a step consisting in printing layers of the three-dimensional object from 50 to 99 wt. % of a polymeric material comprising at least one poly(aryl ether ketone) polymer (PAEK), and optionally at least one poly(biphenyl ether sulfone) polymer (PPSU) and/or at least one poly(ether imide) polymer (PEI), and at least one nitride (N), preferably a boron nitride (BN).
