Cellulose has three hydroxyl groups with different reactivity. By substitution reaction, trimethylsiloxyl-, vinyldimethylsiloxyl-, allyldimethylsiloxyl-, phenyldimethylsiloxyl-, 3,3,3-trifluoropropyldimethylsiloxyl- and tris(trimethylsiloxy)siloxylcellulose were synthesized IR, NMR, and elemental analysis were used for confirming their structures, degree of substitution (D.S.) and the reactivity of siloxylation agent, respectively. The D.S. values were 2.5, 2.2, 2.1, 2.2, 2.6, 0.7 for the corresponding siloxylcellulose.
