Synthesis of Highly Sulfonated Aliphatic Polyester via Michael Reaction

Poly(butylene succinate) (PBS) is regarded as one of the most promising biodegradable aliphatic polyesters,however it’s highly hydrophobic and lack of reactive functional. Therefore, we synthesized for the first time a highly hydrophilic PBS by Michael addition of unsaturated poly(butylene fumarate) with the addition of Sodium bisulfite. The sulfonation degree was calculated by 1H NMR spectra and CHNS Elemental Analyzer
