    • PROBLEM TO BE SOLVED: To provide a method for producing a material with high barrier properties. SOLUTION: Disclosed is a method for producing a material with high barrier properties to gas and liquid containing a thermoplastic matrix and a predetermined nano particle compound. The material is obtained by introducing the compound into a medium for polymerizing the matrix. The compound is obtained by a process including the following successive steps: (a) precipitating, in an acid medium, a compound based on zirconium phosphate and/or titanium phosphorate using, as a starting material, a mixed compound based on phosphoric acid and a zirconium compound and/or a titanium compound or titanium and zirconium (titanium and/or zirconium is in the oxidation state of IV valent); (b) crystallizing the compound; and (c) treating the crystallized compound in a liquid medium of pH3-9.

    • The invention relates to thermoplastic compositions comprising a polymer matrix and an additive which modifies the rheological behavior of the matrix in the molten state. The purpose of the invention is to provide a preferably non-reactive additive which can be dispersed in the matrix and which can be used to obtain a good compromise in terms of rheological properties/mechanical properties. According to the invention, the additive is a hyperbranched polymer which is functionalized by R radicals, R being a radical of the following type: substituted or non-substituted hydrocarbon, of the silicon type, linear or branched alkyl, aromatic, arylalkyl, alkylaryl or cycloaliphatic, which can comprise one or more unsaturations and/or one or more heteroatoms. Preferably, the composition does not contain hyperbranched polymers which produce therein a reduction in the molar mass of matrix M which is greater than or equal to 7% in relation to a sample composition which comprises matrix M but which does not contain hyperbranched polymer additive(s). Said mass measurement is taken preferably using a predetermined protocol P. The invention is suitable for molding, extrusion, engineered plastics, wires and fibers.
