Web4 de mai. de 2016 · The automatic batch MALS analyses of a series of poly (sodium acrylate-co-acrylamide) (30:70 mol %) in 1.0 M NaCl show a non-linear Mark-Houwink relation in the MW range of 1.2 × 10 6 to 12.6 × 10 6 g mol −1. 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 or the Mark-Chrystian equation gives a relation between intrinsic viscosity and molecular weight : From this equation the molecular weight of a polymer can be determined from data on the intrinsi…
