The process of apply of compound stabilizers for organic polymers siliconicos

摘要

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.
