Three nylon-9 samples with Mη= 20400, 12900 and 7100 were fractionated twice into 20 fractions using phenol as solvent and methanol as precipitant. Number average molecular weights Mη,were determined by titration of carboxyl groups in benzyl alcohol at 175℃ and viscosity measurements were carried out in phenol-acetic acid mixed solvent (2:1 by tveight) at 25℃.
