Abstract
Disclosed herein is a thermoplastic cellulosic composition for preparing a cellulose-based masterbatch and/or a cellulose-based fiber with a networked structure. In one example, the thermoplastic cellulosic composition includes an esterified cellulose present in a range of about 80 wt % to about 95 wt %, polyethylene glycol present in a range of about 4.5 wt % to about 12 wt %, a tri-functional cross-linking agent present in a range of about 0.01 wt % to about 3 wt %, an initiator present in a range of about 0.01 wt % to about 0.15 wt %, and a dispersing agent present in a range of about 0.01 wt % to about 5 wt %.

8. A cellulose-based masterbatch with a networked structure, comprising:
-
an esterified cellulose in a range of about 80 wt % to about 95 wt %; polyethylene glycol in a range of about 4.5 wt % to about 12 wt %; a tri-functional cross-linking agent in a range of about 0.01 wt % to about 3 wt %; an initiator in a range of about 0.01 wt % to about 0.15 wt %; and a dispersing agent in a range of about 0.01 wt % to about 5 wt %, wherein each of the tri-functional cross-linking agent has three functional groups, and at least part of the tri-functional cross-linking agent has its three functional groups respectively connected to the molecular chain of the esterified cellulose molecule or the polyethylene glycol molecule, thereby forming the networked structure. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 19)
