Draw the structures of phthalic anhydride, ethylene glycol, and glycerol. Draw the polymer that results from phthalic anhydride & ethylene glycol. Draw the polymer that results from phthalic anhydride and glycerol. Are these addition or condensation polymers? Describe and explain the differences between the polymers formed from the reaction of phthalic anhydride with ethylene glycol versus phthalic anhydride with glycerol.
