Thermosetting resins similar to Bakelite (Section 31.7) have also been prepared from renewable
feedstocks. One method uses cardinol, the major constituent of the liquid obtained from roasted
cashew nutshells. What polymer is obtained when cardinol is treated with formaldehyde (H2C=O)
in the presence of a proton source?

cardinol
Nomex, another aromatic polyamide (compare aramid), is prepared by polymerization
of 1,3-benzenediamine and the diacid chloride of 1,3-benzenedicarboxylic acid. The
physical properties of the polymer make it suitable for high-strength, high-temperature
applications such as parachute cords and jet aircraft tires. Draw a structural formula for
the repeating unit of Nomex.
