Stabilizing composition for organic polymers. |
摘要 |
<p>A stabilizing composition for thermoplastic organic polymers containing measured quantities of: (a) a sterically hindered phenol; (b) a triarylphosphite; and (c) a dialkylthiodipropionate. Stabilized polymer compositions are also described containing a thermoplastic organic polymer, in particular a polyolefin, and a stabilizing quantity of said stabilizing composition, which possess excellent characteristics in relation to their melt flow index and colour when subjected to repeated extrusion and in relation to their long-term thermal stability.</p> |
