    摘要: These compositions based on semi-crystalline thermoplastic resin and on ABC block copolymers result in materials or in items which exhibit an impact strength, an elongation at break, a resistance to cracking and to deformation under stress, and a thermal behavior which are improved with respect to semi-crystalline resin or resins alone or mixed with conventional impact additives, while retaining a high modulus and thus a degree of stiffness. They are generally suitable for the preparation of items or articles, such as sheets, films, pipe sheathings, tubings, pipes, yarns, strands, cable sheathings, bracing wires, leaktight sheathings, sleeve tubes, both mono- and multilayer, shaped components, molded panels, thermoformed articles, sections, bottles or powders for coating substrates. The materials or items obtained from these compositions exhibit a characteristic morphology visible in electron microscopy.

    摘要: Thermosetting resins and thermosetting composites comprising the thermosetting resins are hot-formable. The compositions result from contacting at least one thermosetting resin precursor with at least one hardener selected from acid anhydrides in the presence of at least one transesterification catalyst. The thermosetting resin precursor includes hydroxyl functions and/or epoxy groups, and optionally ester functions, and the total molar quantity of the transesterification catalyst is between 5 and 25% of the total molar quantity of hydroxyl and epoxy contained in the thermosetting resin precursor. Methods for manufacturing articles comprising the thermosetting resins and methods for recycling the thermosetting resins are also disclosed.

    摘要: A graft polymer PG includes a polymer backbone P and at least one side graft G linked to the polymer backbone, the graft G having the general formula (1): in which R1 and R2 represent, separately from one another, straight or branched, unsaturated or saturated hydrocarbon groups, such that the total number of carbon atoms in groups R1 and R2 is between 2 and 110; X represents an amide, amino-acid, urea or urethane function, the graft G being linked to the polymer backbone P via the sulphur atom. The graft polymer PG is a polymer that allows thermoreversible cross-linking and can be used in many fields such as coatings, paints, thermoplastics, adhesives, lubricants, fuels, inks, cements, construction materials, rubbers and bitumens. The graft polymer PG can be used in particular for thermoreversibly cross-linking bitumen/polymer compositions and thus for reducing coating, spreading and/or compaction temperatures during the production of bituminous coated materials.
