一般描述

对苯二甲酰氯是一种源自对苯二甲酸的高反应性酰氯。它在聚合物合成中用作交联剂。对苯二甲酰氯与双官能团α,ω-二氨基聚苯乙烯发生缩合反应,沿着聚合物主链生成含有酰胺键的扩链聚苯乙烯。它与牛血清白蛋白发生界面反应,形成交联薄膜

应用

对苯二甲酰氯通过环状取代 (4-羟基苯基)对苯二甲酸酯的二氰酸酯化合物进行热环三聚反应,以用于合成液晶热固性化合物

Combining polymers with small amounts of stiff carbon-based nanofillers such as graphene or graphene oxide is expected to yield low-density nanocomposites with exceptional mechanical properties. However, such nanocomposites have remained elusive because of incompatibilities between fillers and polymers that are

Poly(ester amide)s are attracting attention because they potentially have excellent thermal and mechanical properties as well as biodegradability. In this study, we synthesized a series of novel poly(ester amide)s by introducing γ-aminobutyric acid (GABA) regularly into polyesters, and investigated their
