  接头部分对线性二聚苯并三唑衍生物作为透明聚酰亚胺薄膜的高稳定性紫外线吸收剂的影响

  摘要：

  在这项研究中，我们为需要长时间高温过程的聚合物（例如聚酰亚胺（PI））开发了一系列高度稳定的紫外线吸收剂。通过将单体与不同的连接基团（苯基，二硫键，联苯）连接，可以合成三种类型的线性二聚羟基苯基苯并三唑衍生物。单体之间的排列受引入二聚羟苯基苯并三唑衍生物中的连接基部分类型的影响。结果，分子间的相互作用发生变化，从而导致热稳定性和溶解度的变化。这些结果表明，与单体相比，二聚羟基苯基苯并三唑衍生物具有显着的稳定性。尤其是，一种新型的带有苯基接头（PBT）的二聚紫外线吸收剂表现出了出色的稳定性，适用于高温工艺。
