What is Polyurethane Synthesis and Properties about?

The main chemical reaction for synthesizing polyurethane involves a diisocyanate reacting with a polyol to form urethane linkages, constituting the polymer backbone. Aromatic isocyanates are more reactive than aliphatic isocyanates due to electron delocalization within the aromatic ring, which stabilizes positive charge and increases electrophilicity. One way to produce polycarbonate polyols involves a transesterification reaction between a dialkyl carbonate and a diol, forming the polycarbonate structure a
