Hyperbranched thermolabile polycarbonates derived from a A₂+B₃ monomer system

Hyperbranched polycarbonates were synthesized successfully via the A₂ + B₃ route by the reaction of a bis(carbonylimidazolide) with triethanolamine. These polymers containing the carbonate group as thermolabile moiety are decomposing into volatile products at around 200°C. The polymers were characterized with ¹H/¹³C NMR spectroscopy, SEC, DSC and TGA techniques.
