Thermally reworkable epoxy resins prepared through a Diels-Alder reaction are described herein. A maleimide component is reacted with an electron donating component having a furan ring attached to an epoxy ether to produce the epoxy resins. The epoxy component generated by this method can be cured with different diamines lo form a robust network of epoxy material. The robust epoxy material is used as a reversible thermoset and as an adhesive. The robust epoxy network is heated at 90° C. temperature in a retro Diels-Alder fashion to produce colorless starting materials of the maleimide component and the furan component.
本文描述了通过 Diels-Alder 反应制备的热可再加工环氧树脂。马来酰亚胺成分与具有连接到环氧醚的呋喃环的电子捐赠成分反应,生成环氧树脂。用这种方法生成的环氧树脂成分可以用不同的二胺固化,形成坚固的环氧树脂材料网。这种坚固的环氧材料可用作可逆热固性材料和粘合剂。在 90° C 的温度下,以复古的 Diels-Alder 方式加热坚固的环氧网络,生成马来酰亚胺组分和呋喃组分的无色起始材料。
