概要

• 論文の詳細を見る

• It is shown that Na-PMA and Na-CMC molecules in dilute aqueous solution are degraded during the usual viscosity measurements with a capillary viscometer, and a solution exposed to UV light exhibits an optical absorption maximum at about 270 nm. Polymer degradation proceeds even with time of rest alone, and the rate constant of the degradation increases with decreasing polymer concentration. Consequently, it is shown that the reduced viscosity of a solution of a considerably degraded polymer exhibits a maximum value at a finite concentration, below which the reduced viscosity decreases.
