Beschreibung
Zusammenfassung:	Disclosed herein are self-healing oligomers according to the structure [UPy - (Dm - U -Dm)(2+q)] - [A(G)(n-1) - Dm]k - Z; wherein UPy, D, m, U, q, A, G, n, k, and Z are defined and described further herein, and wherein the oligomer possesses at least 3 urethane linking groups and comprises a backbone derived from a polyether polyol, a polyester polyol, a poly(dimethylsiloxane), a disulfide polyol, or combinations thereof. Also described and claimed are various compositions containing such oligomers as part of a self-healing component, wherein such compositions also include an optional reactive monomer and/or oligomer component and a photoinitiator component. Yet further described and claimed are articles cured from the compositions elsewhere described using the oligomers elsewhere described. L'invention concerne des oligomères autocicatrisants selon la structure [UPy - (Dm - U -Dm)(2+q)] - [A(G)(n-1) - Dm]k - Z ; dans laquelle UPy, D, m, U, q, a, G, n, k et Z sont définis et décrits davantage dans la description et l'oligomère possédant au moins 3 groupes de liaison uréthane et comprenant un squelette dérivé d'un polyéther-polyol, d'un polyester-polyol, d'un poly(diméthylsiloxane), d'un disulfure de polyol ou des combinaisons correspondantes. L'invention concerne également diverses compositions contenant de tels oligomères en tant que partie d'un constituant auto-cicatrisant, de telles compositions comprenant également un constituant monomère et/ou oligomère réactif facultatif et un constituant photo-initiateur. L'invention concerne en outre des articles durcis à partir des compositions décrites ailleurs à l'aide des oligomères décrits ailleurs.
