Nylon 6,6 is formed from hexamethylene diamine and adipic acid in a reversible reaction with an equilibrium constant k = 170 at 270˚c. a sack of nylon 6,6 chips, intended for fiber extrusion from the melt, has been sitting in a damp warehouse and has gained 5% water (5 g h2o per 95 g dry polymer). if this material is fed to an extruder operating at 270˚c and all the adsorbed water reacts until the polymer comes to equilibrium what will be the final degree of polymerization?
