Definitions

  • the present invention relates to a new process for the preparation of supramolecular materials.
  • supramolecular materials are materials consisting of compounds associated by non-covalent bonds, such as hydrogen, ionic and / or hydrophobic bonds.
  • An advantage of these materials is that these physical bonds are reversible, especially under the influence of temperature or by the action of a selective solvent. It is thus possible to consider using them in fields of application such as coatings (paints, cosmetics, etc.), adhesives, hot melt adhesives and powder coatings.
  • these materials also have elastomeric properties. Unlike conventional elastomers, these materials have the advantage of being able to be fluidized above a certain temperature, which facilitates their implementation, in particular the good filling of the molds, as well as their recycling. Although they are not made of crosslinked polymers but small molecules, these materials, like elastomers, are able to exhibit dimensional stability over very long times and recover their initial shape after large deformations. They can be used to make seals, thermal or acoustic insulators, tires, cables, sheaths, footwear, packaging, patches (cosmetics or dermo-pharmaceuticals), dressings, elastic hose clamps, vacuum tubes, tubes and hoses for transporting fluids.
  • WO 03/059964 discloses a supramolecular material obtained by reacting urea with polyalkyleneimines, polyamines or polyamides which have in common to contain free primary or secondary amine functions.
  • the prepolymer obtained can in particular carry imidazolidone functional groups and free primary or secondary amine functions that can then react with an alkyl halide.
  • the polyamides can themselves be obtained by condensation of polyamines with dimer and matrix of fatty acids.
  • WO 2006/016041 discloses a supramolecular material obtained by grafting compounds bearing an imidazolidone group, such as N-ammoethyl-2-imidazolidone (UDETA) on a polymer such as a PMMA bearing anhydride functional groups.
  • an imidazolidone group such as N-ammoethyl-2-imidazolidone (UDETA)
  • UDETA N-ammoethyl-2-imidazolidone
  • a supramolecular elastomeric material is also disclosed in WO 2006/087475. It comprises molecules containing at least three associative functional groups, such as imidazolidone groups, which can form several physical bonds and which can be obtained by reacting urea on the product of the reaction of a polyamine with triacids.
  • the disadvantage of the preparation processes of the prior art is that they require the use of urea which results in a release of ammonia.
  • it is necessary to strictly control the operating conditions such as the purity of the reagents, their order of introduction, the duration and temperature of the reactions, and than the homogeneity of the mixture.
  • the oligoamidoamine derived from fatty acid obtained by polycondensation of a polyamine such as diethylene triamine, DETA, or triethylene tetraamine, TETA, and a fatty acid must meet very specific criteria in terms of purity and degree of polycondensation to lead to an elastomer.
  • the Applicant has now developed a new process for synthesizing supramolecular materials which is easy to implement and does not lead to an evolution of ammonia, unlike processes using urea as a reagent. This process also makes it possible to obtain materials containing molecules having a particular tree structure capable of conferring on them very varied properties depending on the proportion of the reagents used for their synthesis.
  • these numbers are easily adjusted by the choice of raw materials and by the use of an appropriate stoichiometric ratio, one can optionally and in a controlled manner, a semi-crystalline or amorphous solid, a viscoelastic liquid or an optionally thermoplastic elastomeric material. More specifically, when the average functionality of the monomers is low, essentially linear molecules having a viscoelastic behavior and possibly having a semicrystalline or amorphous solid phase are produced, while forming networks possibly comprising an insoluble fraction and exhibiting elastomeric properties when this functionality is high. It is also possible to obtain materials with a compromise of properties such as self-repair / creep resistance or fluidity / tear resistance.
  • thermoplastic elastomer that is to say of a material capable, at room temperature, of being able to be subjected to uniaxial deformation, advantageously at least 20% for 15 minutes, then recover, once the stress is released, its initial dimension, with a remanent deformation less than 5% of its initial dimension, and which can be put or reformed at high temperature.
  • the novel process according to the invention may also make it possible to obtain self-healing materials, that is to say, capable, once cut, torn or scratched, of repairing by simple re-contacting of the fractured surfaces without the need to heat neither apply significant pressure nor perform any chemical reaction, the repaired material retaining elastomeric properties.
  • the method according to the invention consists in reacting, in a first step, a first compound containing a high proportion of at least trifunctional molecules on a second at least bifunctional compound, in non-stoichiometric proportions leaving free functions on the first compound to obtain a material which is reacted, in a second step, with a compound carrying one or more associative groups.
