Preparation of non-isocyanate polyurethanes from epoxy soybean oil: dual dynamic networks to realize self-healing and reprocessing under mild conditions

Abstract

This work introduces dual dynamic covalent bonds in the network of a non-isocyanate polyurethane prepared using a cyclic carbonate derived from CO 2 to realize self-healing and reprocessing at a low temperature (50 °C) or under UV light.
