ALL CURRENT methods for the determination of diffusion coefficients of gases dissolved in liquids suffer from two main disadvantages. Firstly, each measurement requires a period of hours or even days to complete, and secondly, the methods are somewhat limited in their application [ 11. A critical re
A rapid method for determining the molecular weight distribution of polymers has been the aim of polymer chemists for a long time. The method presented here requires less tban two hours, including dissolution of the polymer. It is an exteneion of a photoelectric turbidimetric technique presented by
