The morphology of polyacrylamide has been studied by electron microscopy. Single spherical molecules of polyacrylamide can be obtained by spray technique from very dilute solution in water-n-propanal mixture. The molecular weight and molecular weight distribution were calculated using electron microscopical method. The influence of percentage of solvent-precipitant mixture
concentration of solution and method of spray on the morphology and the results of calculation have been discussed.
