2) One of the most common consumer plastics is PET (polyethylene terephthalate), which is used extensively in containers for food and beverage products. Coca-Cola has recently come up with a biobased source of ethylene glycol for synthesizing this polymer, however, the terephthalic acid is still derived from petroleum sources. A sustainable source of terephthalic acid is therefore highly desired. One candidate is 2,5-furandioic acid. Draw the repeat unit for the resulting sustainable polyester derived from 2,5furandioic acid and ethylene glycol.

11c. Nylon 6 and poly(ε-caprolactone) have similar polymer backbone structure with one carbonyl, 5 methylene and a heteroatom, nitrogen or oxygen, respectively. Each is able to undergo crystallization. However, their thermal transition temperature differs significantly. The glass transition temperature (Tg) for Nylon 6 is 52 °C, whereas the Tg for poly(εcaprolactone) is 112 degree lower than Nylon 6 at – 60 °C. Similarly, the melting temperature (Tm) for Nylon 6 is 223 °C, whereas the Tm for poly(εcaprolactone) is 60 °C. Briefly explain the significant differences in the thermal properties of these two polymers.

Chemicals for which the commercially important plastic resins are derived are themselves derived from natural products that are quite plentiful;These raw materials include coal, water lime stone, sulfur, salt and petroleum. True or false.
