Ultrasonic velocity studies were undertaken on solutions of cellulose acetate phthalate in alkali metal hydroxides LiOH, NaOH and KOH and water mixture in the concentration range 0-2.5% by weight at frequency of 3 MHz in three different temperatures, 303 K, 313 K, 323 K. The observed non-linear increase in ultrasonic velocity with increase of cellulose acetate phthalate concentration is attributed to the polymer-ion interaction in higher electrolytes.

Abstract


Ultrasonic velocity studies were undertaken on solutions of cellulose acetate phthalate in alkali metal hydroxides LiOH, NaOH and KOH and water mixture in the concentration range 0-2.5% by weight at frequency of 3 MHz in three different temperatures, 303 K, 313 K, 323 K. The observed non-linear increase in ultrasonic velocity with increase of cellulose acetate phthalate concentration is attributed to the polymer-ion interaction in higher electrolytes.
