A polyamide was prepared by bulk polymerization of hexamethylene diamine (11.525 g)with adipic acid (14.6 g) at 300 C. Analysis of the whole reaction product showed that itcontained 2.0×10-3 mol of carboxylic acid groups. Evaluate the number-average molar mass,Mn, of the polyamide, and also estimate its weight-average molar mass, Mw, by assuming thatit has the most probable distribution of molar mass.
