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.
