Abstract
A study is made of the distribution of integral intensities of absorpt ion bands due to stretching vibrations of hydroxy groups at 3200-3700 cm(-1) and carbonyl groups at 1740-1750 cm(-1) in infrared spectra of highly substituted (c(a) = 60-61.5%) cellulose acetates, acetomaleates , and acetophthalates in methylene chloride solutions. The observed va riations in the distribution of the primary (C6) and secondary (C2 and C3) hydroxy (or carbonyl) groups are interpreted in terms of their re lative reactivity in the stages of cellulose activation and acetylatio n.
