    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. The inventive polymer material can be extruded, co-extruded, injected, blown, moulded, overmoulded, calandered, thermoformed. It can be used to produce articles such as tubes, films, plates, extruded strings, bottles, containers. The inventive polymer material can also be mixed with other materials such as other polymers, thus it is used for example as impact modifier or rheology regulator. The invention further concerns the use of said polymer material as compatibility agent in a composition comprising among others at least two polymers belonging to different classes of polymers.

    摘要: The invention relates to materials having rubber-like elasticity and comprising molecules with a mass of between 9 and 9000 g/mole, all or part of said molecules having at least three groups (also known as associative groups) that can associate by means of noncovalent interactions. The inventive material, which comprises non-polymerised and non-chemically-crosslinked small molecules, has rubber-like elasticity properties. In one embodiment of the invention, the material has rubber-like elasticity at ambient temperature. Above a certain temperature, the material flows like a simple liquid. The material is thermoreversible, i.e. a material with rubber-like elasticity can be obtained once again by means of cooling. In addition, the invention comprises a self-healing material that is potentially recyclable, which is never the case with a chemically-crosslinked elastomer. According to one embodiment of the invention, the molecules forming the inventive material bear associative groups having formula (1), in which A denotes oxygen, sulphur or NH, whereby the carbon atoms on formula (1) can be substituted. A preferably denotes oxygen. Advantageously, the material comprises (i) molecules having at least 3 associative groups and (ii) molecules having a single associative group. Moreover, the molecules are preferably obtained from fatty acid derivatives.
