  • Patent number: 11021619
    Abstract: An oligomer bearing at least one crosslinkable ethylenic unsaturation and at least one ionic bond comprises in its structure at least one aminoacrylate group and at least one tertiary amine in a form salified with at least one carboxylic acid. Also described are a process for preparing a solution of the oligomer in a reactive diluent, a crosslinkable composition comprising the oligomer, the use thereof as binder in crosslinkable compositions for temporary-use water-removable materials in coatings, hydrogels and 3D object printing, and the crosslinked material which results from polymerizing the oligomer. As a temporary-use material, the cured oligomer can be easily removed after a temporary function, by simple cleaning with water and optionally at a suitable temperature greater than the glass transition temperature of the crosslinked product.

  • Publication number: 20170044361
    Abstract: The present invention relates to a composition containing, besides a thermosetting resin of epoxy type and/or a hardener, at least one vitrimer effect catalyst and at least one polyol selected from linear, branched or cyclic alkanes containing at least two hydroxyl functions. This composition enables the manufacture of vitrimer resins, that is to say resins that can be deformed in the thermoset state. It also relates to an object obtained from this composition and also to a process for deforming this object.
