Synergistic stabilizer compositions are employed to stabilize halogen-containing vinyl polymers from, for example, degradation and discoloration. The stabilizer compositions comprise a dihydropyridine or polydihydropyridine, and at least one of an aminoalcohol of formula (3)
wherein Y is a substituted or unsubstituted C1-C36 alkyl, aryl, alkaryl, or aralkyl group, R1 and R2 are each independently hydrogen or a substituted or unsubstituted C1-C36 alkyl, aryl, alkaryl, or aralkyl group, with the proviso that Y, R1, and R2 are substituted so as to provide the aminoalcohol with two or more hydroxy groups; or a perchlorate salt.
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。稳定剂组合物包括二氢吡啶或多二氢吡啶,以及至少一种式 (3) 的氨基醇
其中 Y 是取代或未取代的 C1-C36 烷基、芳基、烷芳基或芳烷基,R1 和 R2 各自独立地为氢或取代或未取代的 C1-C36 烷基、芳基、烷芳基或芳烷基,但 Y、R1 和 R2 被取代,以使氨基醇具有两个或多个羟基;或高氯酸盐。
