Preparation of amphiphilic networks by Diels‐Alder reactions between oligo(butyl methacrylate) with furan end‐groups and a poly(ethylene oxide‐co‐acetylenedicarboxylate)

A butyl methacrylate oligomer with furan end‐groups was synthesized by ozonolysing a poly(butyl methacrylate‐ co ‐butadiene) latex. The end‐groups of this oligomer were amidated with aminomethylfuran to give a coagulated mass of derivatized oligomers. This furan functional oligomer was then mixed with poly(ethylene oxide‐ co ‐acetylenedicarboxylate) and heated at 60°C or 125°C. The material cured at 125°C was found to contain a higher gel fraction (55 wt.‐%) than that cured at 60°C (30 wt.‐%).
