Structure formation in solutions of cellulose in n-methylmorpholine n-oxide and during its precipitation
- 21 Downloads
On congealing of cellulose solutions in N-methylmorpholine N-oxide hydrates, spherulites of radial or annular structure arise, consisting of polymer and solvent.
Depending on the nature of the solvent, a dense, homogeneous structure or a cellular structure is formed during precipitation of cellulose from solutions.
