CARBOSILAN-SILOXANE DENDRYMERS OF THE FIRST GENERATION Russian patent published in 2019 - IPC C08G77/16 C08G77/04 C07F7/08 C07F7/12 

FIELD: chemistry.

SUBSTANCE: invention relates to the new functionalized organosiloxane polymers having the dendrimeric branched structure as the dendrimer core containing the cyclooctasylsequioxane fragment. Proposed are the new functionalized carbosilane-siloxane dendrimers of the first generation, in the outer layer containing a corresponding amount of alkyl and hydroxyl groups of the general formula T₈(-CH₂-CH₂-Si(Alk_2.375OH_0.625))₈, where T₈=(SiO_1.5)₈.

EFFECT: obtaining of new carbosilane-siloxane dendrimers with alkyl substituents of various lengths in the outer layer not having the polydispersity and capable of further transformations due to the hydroxyl groups presence in the outer layer at silicon atoms, and, at that, sufficiently stable during storage.
