    摘要: The invention concerns a polymer material consisting of macromolecular chains bound by hydrogen bonds, wherein: the macromolecular chains consist of a polymer skeleton whereon is fixed by at least one covalent bond a modifying agent, the modifying agent comprising, assembled in a common molecule, one or more associative groups capable of being bound by hydrogen bonds and one or more reactive groups capable of forming covalent bonds with the polymer skeleton, at least one of the associative groups of the modifying agent is an imidazolidone heterocycle, the macromolecular chains bear on average, 1 to 10 imidazolidone groups per chain. The average number of imidazolidone groups to be introduced into the macromolecular chains depends both on the average mass of said chains and the final properties desired for the material.

    摘要: The present invention relates to a method for synthesizing a supramolecular material comprising: 1—the reaction of at least one carboxylic diacid, or ester or chloride of such a diacid, with, on the one hand, at least one modifier compound bearing both reactive functional groups capable of reacting with the carboxylic acid, ester or acid chloride functional groups and associative groups capable of associating with one another by hydrogen bonds, in a molar ratio of the reactive functional groups to the carboxylic acid, ester or acid chloride functional groups of between 0.10 and 0.50, and, on the other hand, at least one polyamine, said reactions being carried out successively or simultaneously, and 2—the reaction of the polyamide obtained at the end of step 1 with urea. The present invention also relates to the resulting material, and also to the uses thereof.

    摘要: A process for characterizing a copolymer of ethylene and vinyl acetate (EVA) using a differential calorimetry analysis technique. This process is determining one or more values of characteristic(s) of a sample of EVA copolymer, one of which is a level of crosslinking of the sample. The process makes it possible to determine not only the degree of crosslinking, but also the vinyl acetate content and the molecular mass of an EVA sample, in a simple, rapid, easy and precise manner.

    摘要: A compound includes at least one group Q and at least one group A linked together by at least one “spacer” group Sp, in which: group Q includes a dipole containing at least one nitrogen atom, preferably a nitrile oxide, nitrone, or nitrile imine function; group A contains at least one nitrogen atom, and is preferably an imidazolidinyl, ureyl, bis-ureyl, ureido-pyrimidyl, and triazolyl group; and Sp is an atom or a group of atoms forming a link between Q and A, preferably, a linear, branched or cyclic hydrocarbon-based optionally substituted chain, and may contain one or more aromatic radicals and/or heteroatoms. The compound may react with an unsaturated polymer forming a covalent bond with the polymer. The compound is useful for providing good interaction between fillers and polymers by establishing labile, non-covalent bonds between the polymer chains and the filler, thereby limiting processing problems.
