Thiol-Michael addition between AMS-maleimide and oligoPBAT-dithiol Beforehand, vacuum-dried AMS-maleimide was dissolved in DMAc/LiCl. AMS-maleimide was first placed into a three-necked round-bottomed flask. Dried DMAc was then added. Under a flow of argon, the resulting suspension was stirred for 45 min at 125 °C. After cooling down to 100 °C, LiCl was added. AMS was then rapidly dissolved. After cooling down to 30 °C, oligoPBAT-dithiol was added (Figure ). Thiol and maleimide groups were in an equimolar ratio. Then, 1 molar equivalent, relative to thiol and maleimide groups, of TEA was then added. The solution immediately turned red, and a brownish solid was rapidly formed. After 20 minutes of stirring at 30 °C, the mixture was poured in a large volume of ethanol, filtered, washed with ethanol, and then dried at 40 °C under vacuum for around 15 h. Synthesis for the kinetic evaluation of the Thiol-Michael addition based on a model system.
