Abstract

Non-isocyanate polyurethanes prepared using cyclic carbonates derived from epoxy soybean oil and CO₂ can exhibit the reprocessing ability and facilitate the realization of carbon neutrality, but the relatively high temperature required for the reprocessing is not conducive to application. In this work, a NIPU with a dual dynamic network was designed to achieve reprocessing and self-healing under mild conditions.
