28 Bakelite, a durable plastic used for the casing of early radios and TVs, was the first of the thermosetting polymers. It is a highly cross-linked polymer formed from the acid-catalyzed polymerization of phenol and formaldehyde. Because it is much darker than Melmac, Bakelite's range of colors is limited. Propose a structure for Bakelite. a. Draw the structure of a short segment of PHB. b. Draw the structure of a short segment of PHBV with alternating monomers.
