85. Nylon is synthesized via the polycondensation reaction. For example, the Nylon 6,6 is from the
condensation reaction of hexamethylenediamine and adipic acid. To obtain the polymeric product
with good physical properties, the conversion of the condensation needs to be above 99% to achieve
the high molecular weight. Accordingly, when we select the monomer for the production of Nylon,
what is the lower limit of the equilibrium constant?
