Abstract
Disclosed herein is a thermoplastic cellulosic composition for preparing a cellulose-based masterbatch and/or a fiber with an improved breaking elongation. In one example, the thermoplastic cellulosic composition includes an esterified cellulose present in a range of about 77 wt % to about 95 wt %, polyethylene glycol present in a range of about 4.5 wt % to about 15 wt %, a bifunctional reactant 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 %.
Claims19
A thermoplastic cellulosic composition, comprising:
- an esterified cellulose in a range of about 77 wt % to about 95 wt %;
- a polyethylene glycol in a range of about 4.5 wt % to about 15 wt %;
- a bifunctional reactant 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 %.
A cellulose-based masterbatch, comprising:
- about 77 wt % to about 95 wt % of a esterified cellulose;
- about 4.5 wt % to about 15 wt % of a polyethylene glycol;
- about 0.01 wt % to about 3 wt % of a bifunctional reactant;
- about 0.01 wt % to about 0.15 wt % of an initiator;
- and
- about 0.01 wt % to about 5 wt % of a dispersing agent, wherein each of the bifunctional reactant has two terminal reactive end-groups, and at least part of the bifunctional reactant has its two reactive end-groups respectively connected to the molecular chain of two esterified cellulose molecules such that the esterified cellulose molecules form a matrix with a continuous phase and the polyethylene glycol molecules distribute across the matrix.
A cellulose-based fiber having a breaking elongation no less than about 28%.
