    Effect of acetylation site on orientation birefringence of cellulose triacetate

    The effect of a substitution site on orientation birefringence for cellulose triacetate (CTA) was investigated by the addition of xylan ester. Since CTA has three substitution sites (C-2, C-3, and C-6) while x...
