The viscosity behaviour of barium, lead and copper polymethacrylates in 1.0 M hydrochloric acid at 30-degrees-C has been reported for various concentrations. The concentration range studied conform to the viscosity behaviour explained on the basis of ionic radii. Barium polymethacrylate has lower viscosity than that for lead and copper polymethacrylates.
