Abstract: The present invention relates to a liquid (meth)acrylic syrup for impregnating a fibrous substrate; a viscous liquid syrup mainly containing methacrylic or acrylic components, and preferably hollow beads; to a process for manufacturing such a syrup; to a process for impregnating a fibrous substrate or long fibers with said viscous liquid syrup; to a fibrous substrate preimpregnated with said syrup, which is useful for manufacturing mechanical or structured parts or products; to a manufacturing process for manufacturing mechanical or structured parts or articles; and to three-dimensional mechanical or structured parts obtained by this process. The invention makes it possible to significantly reduce the exothermic peak during the polymerization of the syrup, to reduce the residual content of monomer at the end of polymerization, and to obtain parts made of composite material that have few or no defects.

Abstract: The present invention relates to a (meth)acrylic mixture for impregnating a fibrous substrate, characterized in that it comprises: a) a first dispersion comprising at least one (meth)acrylic polymer obtained by emulsion polymerization of one or more (meth)acrylic monomers, b) a second dispersion comprising at least one flame retardant. The invention also relates to a method for impregnating a fibrous substrate with a (meth)acrylic mixture of this kind, and to a method for manufacturing mechanical parts or structured elements, or articles, from the (meth)acrylic mixture. Another objective of the invention is a mechanical part or a structured element or an article made of composite material, obtained by the implementation of the manufacturing method.

Abstract: A copolymer having amphiphilic blocks includes at least one first hydrophilic block, obtainable from n-butyl acrylate and hydroxyethyl methacrylate monomers, and a second hydrophobic block likely to be obtained from a methyl methacrylate monomer. The copolymer is found to be particularly advantageous for use as an additive for manufacturing a polymer filtration membrane, particularly a PVDF membrane, particularly via a phase inversion method.

Abstract: The present invention relates to an impregnation process for a fibrous substrate, a liquid composition for implementing this process and the obtained impregnated fibrous substrate. The impregnated fibrous substrate is suitable for manufacturing mechanical or structured parts or articles. In particular the present invention deals with an industrial process for impregnating a fibrous substrate or long fibers with a viscous liquid composition containing mainly methacrylic or acrylic components. This viscous composition is called hereafter liquid (meth) acrylic syrup. The invention concerns also a fibrous substrate pre-impregnated with said syrup which is useful for manufacturing mechanical or structured parts or articles. More particular the impregnation of fibrous substrate with the (meth) acrylic syrup is achieved in a closed mould. The present invention concerns also manufacturing process for manufacturing mechanical or structured parts or articles and three-dimensional mechanical or structured parts obtained by this process.
