摘要： Provided is a composition suitable for a process of building a three-dimensional object layer-by-layer by electromagnetic radiation-generated sintering, including at least one poly(aryl-ether-ketone) (PAEK), where the composition has an aromatic ether content of from 0 and 0.4% by mass, based on the total mass of the composition, and an aluminium mass content of lower than 1000 ppm. The composition may be used in process for building an object comprising sintering the composition with electromagnetic radiation. The present invention also includes a three-dimensional object obtained by such a process. A process for preparing the composition is also provided.

摘要： A method for the manufacture of polyether ketone ketone (PEKK), including the steps of: reacting 1,4-bis(4-phenoxybenzoylbenzene) and/or diphenylether with at least one difunctional aromatic acyl chloride, in a reaction solvent and in presence of a Lewis acid, to obtain a product mixture including a PEKK-Lewis acid complex; contacting the obtained product mixture with a protic solvent, so as to form a dispersion that includes a liquid phase including Lewis acid and a second phase, e.g., a solid phase, including PEKK; and separating the second phase from the liquid phase by centrifugal filtration, so as to recover a crude PEKK and a effluent containing Lewis acid, wherein step (iii) includes a step of centrifugal filtration.

摘要： A method for manufacturing 1,4-bis(4-phenoxybenzoylbenzene), including: reacting terephthaloyl chloride with diphenyl ether in a reaction solvent and in the presence of a Lewis acid, so as to obtain a product mixture including a 1,4-bis(4-phenoxybenzoylbenzene)-Lewis acid complex; contacting the product mixture with a protic solvent, so as to obtain a first phase containing the Lewis acid and a second phase containing 1,4-bis(4-phenoxybenzoylbenzene); subjecting at least the second phase to a solid/liquid separation step by centrifugal filtration, so as to recover solid 1,4-bis(4-phenoxybenzoylbenzene).
