The effects of urea on aqueous solutions of both poly(methacrylic acid (PMA) and poly(acrylic acid) (PAA) have been investigated by using potentiometry, viscometry and study of the fluorescence of Auramine O, a cationic dye. The viscosity behaviour of unionized PMA obtained from direct dissolution o

## Abstract The isoionic dilution method has been used to measure the intrinsic viscosity, [ฮท], of a poly(acrylic acid) (PAA) sample as a function of neutralization degree, __i__, at low ionic strength, __I__ = 1.0 ร 10. The results obtained for the counterion activity are in close agreement with M
