Nylons are strong sythetic fibers commonly used to make clothing and other goods. One of the most common nylons, Nylon 66, is made by the condensation reaction between adipic acid and hexamethylenediamine (hexane-1,6-diamine). Modify the monomers to create one repeat unit of the polymer. NH Incorrect

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.
