Synergistic stabilizer compositions are employed to stabilize halogen-containing vinyl polymers from, for example, degradation and discoloration. The stabilizer compositions comprise an aromatic amine and at least one additional co-stabilizer. The co-stabilizer is a dihydropyridine, a polydihydropyridine, an amino alcohol, a perchlorate, a polyol, a sterically hindered amine, a hydrotalcite, a mercaptan-containing organic compound, or a mixture comprising one or more of the foregoing co-stabilizers. Also described are halogen-containing vinyl polymer compositions comprising an aromatic amine, and articles comprising the polymeric compositions.
增效稳定剂组合物用于稳定含卤乙烯聚合物,防止降解和褪色等。稳定剂组合物包括芳香胺和至少一种辅助稳定剂。助稳定剂包括二氢吡啶、多二氢吡啶、氨基醇、高氯酸盐、多元醇、立体受阻胺、氢化铝酸盐、含硫醇的有机化合物,或包含一种或多种上述助稳定剂的混合物。此外,还描述了包含芳香胺的含卤乙烯聚合物组合物,以及包含该聚合物组合物的物品。
