Substantially colourless, liquid compositions are described which are constituted by a phenolic antioxidant, or mixture of phenolic antioxidants, and at least one phosphine, the compositions being highly resistant to coloration phenomena.
These compositions are effective stabilizers for organic polymers and, when incorporated in the said polymers, have a stabilizing power which is greater than that shown by the phenolic antioxidant or mixture of phenolic antioxidants alone.
描述了由一种酚类抗氧化剂或酚类抗氧化剂混合物和至少一种膦组成的基本无色的液态组合物,这些组合物具有很强的抗着色现象的能力。 这些组合物是有机聚合物的有效稳定剂,当与所述聚合物结合时,其稳定能力大于酚类抗氧化剂或酚类抗氧化剂混合物单独显示的稳定能力。
