The invention relates to oligomers of silane compounds having at least one hydrolysable group and at least one heteroatom bridged to a silicon atom via a sp2-hybridized quaternary carbon atom, as defined herein, a process for preparing such silane compound resins, the use thereof, for example as end-capping agent, crosslinker, and/or adhesion promoter in curable compositions, and curable compositions containing these resins as well as the use of such compositions. L'invention concerne des oligomères de composés de silane présentant au moins un groupe hydrolysable et au moins un hétéroatome ponté à un atome de silicium par l'intermédiaire d'un atome de carbone quaternaire hybridé en sp2, tel que défini dans la description, un procédé de préparation de telles résines de composé de silane, leur utilisation, par exemple en tant qu'agent de coiffage d'extrémité, réticulant et/ou promoteur d'adhérence dans des compositions durcissables et des compositions durcissables contenant ces résines ainsi que l'utilisation de telles compositions.
