Abstract
Provided is a polymer material containing at least one kind of a cellulose derivative having (a) an organosilyl group (the organosilyl group having a first aliphatic group, an unsaturated aliphatic group, or an aromatic group), and (b) an acyl group or a second aliphatic group.
Claims16
A polymer material, comprising:
- a cellulose derivative of formula (1):
- where R1, R2 and R3 are each independently selected from the group consisting of i) a hydrogen atom, ii) an organosilyl group having a first aliphatic group, an unsaturated aliphatic group or an aromatic group, iii) an acyl group and iv) a second aliphatic group, provided that the cellulose derivative includes (a) the organosilyl group and (b) the acyl group or the second aliphatic group, and
- n is a positive integer.
