| 摘要 |
The present invention relates to a composition containing, in addition to a thermosetting epoxy resin and an anhydride hardener, at least one vitrimer-effect organic catalyst. Said composition enables vitrimer resins to be manufactured, i.e., resins that are deformable in the thermoset state. Said invention also relates to a kit for manufacturing said composition, to an object obtained from said composition and to a kit for manufacturing said object. |

1. A composition comprising:
a catalyst comprising a compound of formula (I): in which: X denotes a nitrogen atom or a —CH— group, R1 denotes a hydrogen atom or a C1-C6 alkyl group or a phenyl group that optionally is substituted with a C1-C4 alkyl group, R2, R3 and R4 independently denote a hydrogen atom, a C1-C6 alkyl group, a phenyl group that optionally is substituted with a C1-C4 alkyl group, or an acetyl group, or R1 and R2 form, together and with the atoms to which they are bonded, a saturated or unsaturated heterocycle and/or R3 and R4 form, together and with the atoms to which they are bonded, a saturated or unsaturated heterocycle, a thermosetting resin comprising at least one epoxide function and optionally at least one free hydroxyl and/or ester function, and a thermosetting-resin curing agent selected from carboxylic acid anhydrides. |
