Bis-ethynyl quinoxaline compositions are prepared by the condensation reaction of an aromatic diglyoxyl or dibenzil with an ethynyl-substituted aromatic ortho-diamine. The compositions are useful as polymerizable plasticizers for heterocyclic thermoplastic resins in the fabrication of composites. Polymerizable plasticizers are materials that remain fluid and act as a plasticizer during early stages of fabrication and then polymerize to a rigid resin.
双乙炔喹啉组合物是通过芳香二羟基或二苄基与乙炔取代的芳香邻二胺的缩合反应制备的。这些组合物可用作杂环热塑性树脂的可聚合增塑剂,用于制备复合材料。可聚合增塑剂是在制备的早期阶段保持流动并起增塑作用,然后聚合成为硬质树脂的材料。
