<p>Siliconic compounds, stabilizer for organic polymers, containing in their molecule the aromatic phosphite or phosphonite function and the sterically hindered aminic function, are obtained by making a 2,2,6,6-tetramethyl-piperidinyl-4-oxyalkylene- gamma -alkyldi(alkyloxy)silane, an aliphatic glycol, an aromatic phosphite, phosphonite or diphosphite and possibly an aliphatic mono-hydroxy alcohol interact with each other.</p> |
