Abstract
Stabilizers for organic polymers are disclosed, of the type of sterically hindered phenols or amines, which are obtained by means of the reaction of a sterically hindered phenol or amine bearing in the molecule at least in alkoxysilanol group with a mono- or poly-hydroxy aliphatic alcohol, by a transesterification reaction. The stabilizers so obtained are compatible with the organic polymers, wherein they remain stably.
