Solutions of several samples of polypropiolactone in chloroform (trichloromethane, CHCl3) were studied viscometrically at 30 °C and the following dependence of intrinsic viscosity on molar mass was obtained:
M, kg/mol 145.0 110.0 70.7 59.4 30.5
[n], cm3/g 150 107 58.9 49.1 19.6
Calculate the coefficients of the Mark-Houwink equation.
