Mark–Houwink equation

Index Mark–Houwink equation

The Mark–Houwink equation, also known as the Mark–Houwink–Sakurada equation or the Kuhn–Mark–Houwink–Sakurada equation or the Landau-Kuhn-Mark-Houwink-Sakurada equation gives a relation between intrinsic viscosity and molecular weight M: From this equation the molecular weight of a polymer can be determined from data on the intrinsic viscosity and vice versa.
