“…This phenomenon is very noticeable in polar polymers. The unusually large solvent dependence of the unperturbed chain dimensions has already been reported for cellulose, amylose, and their derivatives by Kamide et al,[5][6][7][8][9] who analyzed literature data available. On the other hand, the existence of a hydrogen bond between the 0-acetyl group in the CA molecule and halogenated hydrocarbons 10 • 11 and the interaction between the 0-acetyl group and aniline or acidic solvents has been proposed 12 on the basis of infrared spectroscopic observations.…”

“…( 1 7 Both X and E should be determined from the measurement of a and a, by using Eqs. (13) and (14), when the a, value is estimated by other methods. By using a = 0,616 and a, = 0,39 for CA (D.S.…”
