Reduced viscosities of Funori extractive, the water-soluble extractive from the red sea weed Gloiopettis tenax, in aqueous potassium chloride were measured at 30°C. as a function of Funori concentration C and KCl concentration x. The family of ηsp/C vs. C curves obtained for different x was essentially similar to that which had been reported for many other polyelectrolytes. From comparison with data for agar-agar some evidence was obtained which indicates the Funori molecule to have a higher charge density than the agar-agar molecule. A parameter, m, in the PALS-HERMANS method of iso-ionic dilution was found to have a value less than unity, which may be attributed to a binding of counterions to the oppositely charged polyion.
