912. For several preparations of polycaprolactam, molar masses have been established and the intrinsic viscosities of their solutions in m-cresol at 25 °C have been determined:
М ×10–3, g/mol 3.50 4.46 7.69 8.6 13.0 15.8 17.6 21.6 25.0 30.8
n], dl/g 0.36 0.43 0.61 0.69 0.87 0.94 1.10 1.25 1.40 1.59
Use these data to find the coefficients of the Mark-Houwink equation for the polycaprolactam/m-cresol system.
