Abstract
Results are given for a comparative study of the structure and distrib ution of hydroxyl groups in samples of cellulose triacetate with low c ontent of mono- and disubstituted glucopyranose units (j = 2.7-2.9) sy nthesized by a heterogeneous procedure entailing activation of cellulo se by acetic acid and a variant with complete or partial replacement o f acetic acid by formic acid in the cellulose activation step. A quant itative method for determining the content and distribution of primary and secondary hydroxyl groups of the polymer is presented and discuss ed for laboratory and industrial samples of cellulose triacetate.
