Disulphide metathesis is an effective bond exchange for catalyst-free vitrimers. Vitrimers incorporating disulphide bonds feature a fast evolution of stress relaxation modulus at moderate temperature and have been achieved with benzoxazine using a simple implementation of onepot solventless Mannich condensation reaction , resulting in a vitrimer appropriate for low temperature applications due to a 𝑇 𝑔 of 40°C and degradation temperature of 252°C.
