Solutions of several samples of polypropiolactone in trifluoroethanol (TFE) were studied viscometrically at 25 °C and the following dependence of intrinsic viscosity on molar mass was obtained:
M, kg/mol 193 167 148 126 92.4 80.0 51.4 38.8
[η], cm3/g 150 130 107 86.5 60.1 49.1 28.5 19.6
Calculate the coefficients of the Mark-Houwink equation.
