Abstract: One subject of the present invention is a composition that combines at least one polyamide having at least one MXD entity, MXD denoting meta-xylylenediamine or a mixture of meta-xylylenediamine and of para-xylylenediamine, with a bioresourced reinforcement. The invention also relates to the conversion of these compositions, by injection moulding or extrusion, into objects that have good mechanical properties, said objects corresponding to technical application specifications such as may be found, for example, in the automotive industry, construction, sport and in electrical or electronic fields.

Abstract: A method for manufacturing 1,4-bis(4-phenoxybenzoylbenzene), including: providing a reactant mixture including terephthaloyl chloride, diphenyl ether and a Lewis acid in a solvent; reacting terephthaloyl chloride with diphenyl ether, so as to obtain a product mixture including a 1,4-bis(4-phenoxybenzoylbenzene)-Lewis acid complex; wherein the 1,4-bis(4-phenoxybenzoylbenzene)-Lewis acid complex is dissolved in the solvent at a 1,4-bis(4-phenoxybenzoylbenzene) weight concentration in the solvent which is higher than the saturation limit of the 1,4-bis(4-phenoxybenzoylbenzene)-Lewis acid complex during at least part of the step of reacting terephthaloyl chloride with diphenyl ether.

Abstract: 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.
