  • Patent number: 12202949
    Abstract: A method for treating a polymer part comprising a step of bringing the part into contact with vapours of solvent(s), capable of at least partially solubilising the part, this contacting step being carried out under vacuum. Application of this method for modifying the roughness of the part and/or functionalising it.

  • Publication number: 20230357521
    Abstract: A process for chemically modifying a polymeric part in order to provide it with flame retardancy properties or to enhance the properties, the process comprising a step of reacting at least one polymeric part comprising at least one polymer of which the reactive groups comprise amine groups and/or hydroxyl groups with a flame retardant compound comprising at least one group that reacts, by nucleophilic substitution or nucleophilic addition, with some or all of the amine groups and/or hydroxyl groups of the polymer or polymers, the reaction being carried out with the compound in gaseous form.

  • Publication number: 20230119701
    Abstract: A process for chemically modifying a polymeric part in order to impart antistatic properties thereto or to improve these properties, comprising the following steps: a step of reacting a polymeric part comprising at least one polymer comprising, as reactive groups, amine groups and/or hydroxyl groups, with a functional compound, also called first compound, comprising at least one isocyanate group and at least one heterocyclic type polymerisable group, the isocyanate groups covalently reacting with all or part of the amine groups and/or hydroxyl groups of the polymer(s), whereby this results in a polymeric part that is covalently bonded to residues of the functional compound; from the heterocyclic type polymerisable groups of the residues of the functional compound, a step of polymerising a second compound comprising at least one heterocyclic type polymerisable group in the presence of a metal complex, the reaction step and the polymerisation step being carried out in the presence of at least one supercritical

  • Publication number: 20230106916
    Abstract: A method for chemically modifying a wood part comprising hydroxyl groups comprising: a first step of covalently reacting all or part of the hydroxyl groups with at least one non-polymeric compound comprising at least one group capable of covalently reacting with a hydroxyl group, whereby the wood part is thus covalently linked to residues of the non-polymeric compound(s); after or simultaneously with the first step, a second step of covalently reacting all or part of the residues of the non-polymeric compound(s) with at least one second compound, the first step and the second step being performed in the presence of at least one supercritical fluid.

  • Publication number: 20230065938
    Abstract: A process for chemically modifying a polymeric part in order to impart flame-retardant properties thereto or to improve the properties, the process comprising the following steps: a step of reacting a polymeric part comprising at least one polymer comprising, as reactive groups, amine groups and/or hydroxyl groups, with a functional compound, referred to as first compound, comprising at least one isocyanate group and at least one vinyl type polymerisable group, the isocyanate groups reacting, covalently with all or some of the amine groups and/or hydroxyl groups of the polymer(s), resulting in a polymeric part bonded, covalently, to residues of the functional compound; using the vinyl type polymerisable groups of the residues of the functional compound, a step of polymerising a second compound comprising at least one vinyl type polymerisable group and at least one group comprising at least one phosphorus atom, the reaction step and said polymerisation step being carried out in the presence of at least one sup

  • Publication number: 20230047059
    Abstract: A chemical modification process for a polymer component comprising at least one polymer comprising, as reactive groups, amine groups and/or hydroxyl groups, the process comprising a step of covalent reaction between some or all of the reactive groups and at least one functional compound comprising at least one group able to react in a covalent manner with said reactive groups, the functional compound(s) being selected from epoxide compounds, anhydride compounds, acyl halide compounds, silyl ether compounds and mixtures thereof, characterised in that the covalent reaction step is carried out in the presence of at least one supercritical fluid.
