ABSTRACT Hyperbranched polymers (HPs), which in terms of structure may be compared to the branching structure of trees, are referred to as tree-like materials, but role of leave in these tree-like polymers is neglected and much attention has only been paid to their branches. In fact, functional groups in these polymers play a vital role the same as the role of leaves in trees. Therefore, in this paper, an attempt has been made to design and synthesize three AB2 monomers containing extra hydroxyl and nitro groups. The benefits of their presence in the structure of produced hyperbranched polyamides (HPs) are investigated. The polymer structure was characterized by FT-IR and 1 H NMR. The solubility of synthesized HPs was studied in different protic and aprotic solvents. The thermal stability of the prepared HPs was investigated by thermogravimetric and differential scanning calorimetric analyses. The photoluminescent properties of the HPs were also investigated.

从 AB2 单元合成和表征新型功能性超支化聚酰胺：额外官能团的影响

摘要 超支化聚合物（Hyperbranchedpolymer，HPs）在结构上可与树的分枝结构相提并论，被称为树状材料，但叶在这些树状聚合物中的作用却被忽视而备受关注。到他们的分支机构。事实上，这些聚合物中的官能团起着至关重要的作用，就像树叶在树木中的作用一样。因此，在本文中，尝试设计和合成三种含有额外羟基和硝基的 AB2 单体。研究了它们存在于生产的超支化聚酰胺 (HP) 结构中的好处。聚合物结构通过FT-IR和1 H NMR表征。研究了合成 HPs 在不同质子和非质子溶剂中的溶解度。通过热重分析和差示扫描量热分析研究了制备的 HPs 的热稳定性。还研究了HPs的光致发光特性。
