Howard describes a model system used to test the molecular weight distribution of acondensation polymer (g. j. howard, j. polym. sci. 37, 310 (1959)): "the polymer sample was an acetic acid-stabilized equilibrium nylon-6,6. analysis showed it to have the following end group composition (in equivalents per 106 g): acetyl = 28.9, amine = 35.3 and carboxyl = 96.5. the number average degree of polymerization is, therefore, 110 and the conversion degree (= extent of reaction) = 0.9909.for nylon-6,6, 99% of the carboxylic acid groups are know to have reacted.
calculate the average of mn, mw and mz.
