Metal Ion-Catalyzed Low-Temperature Curing of Urushiol-Based Polybenzoxazine

open access: yesFrontiers in Chemistry, 2022
In this work, urushiol-based polybenzoxazine is cured by the Lewis acid (FeCl3, AlCl3, and CuCl2) at low temperature instead of high thermal curing temperature. The effect of the Lewis acid on structures and properties of the polymers is revealed.
