Process for the preparation of stabilizers for organic polymers

摘要

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.
