The Osmotic Balance

Abstract

IN the case of polydisperse high polymers, different methods of molecular weight determination give different kinds of average values1. The two most important absolute methods are ultra-centrifuging and measurement of osmotic pressure. In the first case one gets, according to the method of calculation used, either weight averages or so-called Z-averages… (More)
