| 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 2,2,6,6tetramethyl-piperidinyl-4-oxyalkylene-?-alkyl-di(alkyloxy) silane, an aliphatic glycol, an aromatic phosphite, phosphonite or diphosphite and possibly an aliphatic monohydroxy alcohol interact with each other. The invention is also directed to a polymeric stabilized compositions comprising an organic polymer and a stabilizer amount of at least one of the above mentioned siliconic stabilizer compounds.
