Abstract: Yarns, fibers or filaments, in particular based on polyamides, are shaped into a variety of articles, especially ropes and more particularly climbing ropes which have good mechanical properties, especially under both low and relatively high humidity conditions.

Abstract: Novolac resins are incorporated into thermoplastic polyamide compositions for increasing the melt flow index thereof; such compositions containing the novolac resins are useful for the manufacture of plastic shaped articles, in particular by injection molding.

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 wires, fibres and filaments having improved resistance to abrasion, which are suitable, for example, for the production of felts for papermaking machines. In particular, the invention relates to polyamide- or polyester-based wires, fibres and filaments.

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 concerns a method for making yarns, fibres and filaments based on polyamide, and yarns, fibres and filaments obtainable by said method. The invention concerns a method for making yarns, fibres and filaments based on a polyamide composition having a molecular structure for enhancing overall productivity of the spinning process, in particular by improving the capacity for drawing the yarns produced thereby providing, for example, for a single identical spinning speed a much higher yarn meterage produced per time unit after drawing.
