Ozonization products of allylated celluloses such as completely allylated methylcellulose and tri‐O‐allylcellulose, which are insoluble in both organic solvents and water, gave water‐soluble derivatives by alkaline treatment. Infrared (IR) and 13C‐NMR (nuclear magnetic resonance) spectrometries revealed that the products have many carboxyl as well as carbonyl groups. Allyl ethers in allylated celluloses were found to be cleaved by 30–35% during ozonization, whereas alkyl ethers such as methyl and ethyl ethers in cellulose derivatives were completely stable.
