Lexan, a polycarbonate, is a condensation copolymer formed between carbonic acid and bisphenol A. Draw the structure of the dimer. Hint: Water (circled) is eliminated when the bond between the monomers forms.
Polycarbonates (PC) are a group of thermoplastic polymers containing carbonate groups in their chemical structures. Polycarbonates received their name because they are polymers containing carbonate groups (−O−(C=O)−O−).
