Novel morpholino end-capped polyamino-1,3,5-triazines which have general formula (I), wherein R1 is selected from hydrogen, hydrocarbyl, hydrocarbyloxy and a group of formula (II); each R2 is independently selected from hydrogen, oxyl, hydroxy, hydrocarbyl and hydrocarbyloxy; each R3 is independently selected from an alkyl of 1 to 5 carbon atomes; each of R4 and R5 is independently a hydrocarbyl group; n is 2-12; and x is 1-50. Methods for their use as light stabilizers for materials which are subject to degradation (for example, by actinic radiation), stabilizer compositions based on these morpholino end-capped polyamino-1,3,5-triazines and methods for their synthesis are herein described.
L'invention concerne de nouvelles polyamino-1,3,5-triazines à coiffe terminale morpholino, représentées par la formule générale (I), dans laquelle R?1¿ est sélectionné parmi hydrogène, hydrocarbyle, hydrocarbyloxy et un groupe de formule (II); chaque R?2¿ est indépendamment sélectionné parmi hydrogène, oxyl, hydroxy, hydrocarbyle et hydrocarbyloxy; chaque R?3¿ est indépendamment sélectionné parmi un alkyle de 1 à 5 atomes de carbone; chaque R?4¿ et R?5¿ représentent indépendamment un groupe hydrocarbyle; n est compris entre 2 et 12; et x, entre 1 et 50. L'invention concerne également leurs méthodes d'utilisation en tant que photostabilisants destinés à des matériaux pouvant subir des dégradations (par exemple, par radiation actinique), des compositions stabilisantes à base de ces polyamino-1,3,5-triazines à coiffe terminale morpholino, et leurs méthodes de synthèse.
