Title (EN) SELF HEALING COMPOSITION
(FR) COMPOSITION AUTO-CICATRISANTE
Abstract:
(EN) Healing composition comprising a plurality of first microcapsules having a shell and a core, the core comprising a first flowable compound having first functional groups and a plurality of second microcapsules having a shell and a core, the core comprising a second flowable compound having second functional groups, wherein the first functional groups can react with the second functional groups in the absence of a catalyst or activator, wherein the first functional groups are thiol (-SH) groups and the second functional groups are -ene (C=C) groups, self healing polymer composition comprising a polymer media and the healing composition and. shaped article comprising the self healing composition.
(FR) L'invention concerne une composition cicatrisante comprenant une pluralité de premières microcapsules présentant une enveloppe et un noyau, le noyau contenant un premier composé fluide contenant des premiers groupes fonctionnels et une pluralité de secondes microcapsules présentant une enveloppe et un noyau, le noyau comprenant un second composé fluide présentant des seconds groupes fonctionnels, les premiers groupes fonctionnels pouvant réagir avec les seconds groupes fonctionnels en l'absence d'un catalyseur ou activateur, les premiers groupes fonctionnels étant des groupes thiol (-SH) et les seconds groupes fonctionnels étant des groupes –ène (C=C), une composition polymère auto-cicatrisante comprenant un milieu polymère et la composition cicatrisante et l'article conformé comprenant la composition auto-cicatrisante.
