Abstract: The present invention relates to articles with antibacterial and antifungal activity, comprising zinc sulphide. The yarns, fibres, filaments and articles according to the present invention may be used especially in the manufacture of any product liable to be placed in contact with bacteria and/or fungi, for instance clothing, rugs, curtains, bedclothes and medical textile materials. The present invention also relates to the use of zinc sulphide for manufacturing yarns, fibres, filaments and/or articles with antibacterial and antifungal properties.

Abstract: 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<2> radicals, R<2> 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.

Abstract: The invention relates to a novel use of zinc sulfide as agent for combating acarids. The invention also relates to compositions with acarid-combating properties comprising zinc sulfide as additive, in particular polymer compositions, and to yarns, fibers, filaments and articles obtained from these compositions; it is also targeted at liquid or solid compositions for cleaning and/or treating textile surfaces, in particular carpets, including fitted carpets.

Abstract: The invention relates to thermoplastic compositions comprising a thermoplastic polyamide matrix and at least one additive which modifies the interaction between the matrix and an agent. The purpose of the invention is to provide an additive which modifies the interaction between a copolyamide-type thermoplastic copolyamide matrix and at least one agent. The aforementioned additive, which comprises at least one hyperbranched functionalised polymer, is not compatible with the matrix. Moreover, said additive can be used for the controlled modification of the interaction between the thermoplastic copolyamide and an internal or external chemical agent. 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 does not contain hyperbranched polymer additive(s). Said mass measurement is taken preferably using a determined protocol P.

Abstract: The invention relates to a composition comprising at least one polymer matrix and a functionalised additive, obtained by the reaction of a mixture of compounds including at least one multifunctional compound and a functionalised monofunctional compound. Said composition particularly permits the production of threads, fibres, films, filaments, and moulded items.

Abstract: The invention relates to polyamide compositions having improved antistatic behaviour and/or improved hydrophilicity. These compositions are particularly suitable for the manufacture of polyamide-based yarns, fibres and filaments. The compositions comprise polyamide and a modifier containing polyether units, which modifies the antistatic and/or hydrophilic properties.
