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.

i) Which of the following is not true about step-growth polymers? Formation of step-growth polymers usually results in the loss of a small molecule. Step-growth polymers are formed by the reaction of bifunctional molecules. Step-growth polymers can be formed by a free radical mechanism. Step-growth polymers are also known as condensation polymers. Step-growth polymers do not reach high molecular weight until the reaction has gone nearly to completion. ii) Which of the following are not termination methods in radical polymerization?...
