Investigation of thermo-reversibility of polymer crosslinked by reversible covalent bonds through torque measurement

Cyclopentadiene‐functionalized polyketone as self‐cross‐linking thermo‐reversible thermoset with increased softening temperature

“…Such cyclopentadiene‐modified polymers showed de‐cross‐linking at 215°C and re‐processability above 170°C, thus suggesting that, even though at this temperature the DA bonds are only partially broken, the macromolecular chains are free to stretch and slide upon shear. This is further confirmed by a recent study where the authors found out through torque measurements that this thermo‐reversible network has an ideal temperature of 174°C for re‐processability with limited side‐reaction and acceptable flowability …”

Effect of the conversion degree and multiple healing on the healing efficiency of a thermally reversible self‐healing polymer

“…Furan (F) and maleimide (M) are one of the major groups that can be used as diene and dienophile in the DA cycloaddition. Owing to the availability and straightforward process of synthesization, these monomers have been employed in many research works …”

“…Owing to the availability and straightforward process of synthesization, these monomers have been employed in many research works. 2,3,[9][10][11][12][13][14][15] A self-healing polymer based on DA cycloaddition was reported by Chen et al 16 Their system was based on a multi-furan monomer containing four furan groups (4F) and a multi-maleimide monomer consisting of three maleimides (3M). The high melting point of the maleimide, which makes it difficult to dissolve in furan monomers, was one of the problems that they faced in their study.…”
