Synthesis of Thermoplastic Materials Using Cellulose Acetate as a Backbone via Melt Kneading Extrusion.

ABSTRACT: To develop a highly biomass-based thermoplastic resin using cellulose acetate (CA) derived from woody biomass as the base material, cellulose acetate-graft-polylactic acid (CA-g-PLA) composites were successfully synthesized by a transesterification reaction through the melt kneading method using 2-ethylhexanoic acid tin-(II) as a catalyst. Various characterization methods, such as Fourier-transform infrared spectroscopy (FTIR), proton nuclear magnetic resonance (¹H NMR), differential scanning calorimetry (DSC), X-ray diffraction (XRD), and thermogravimetric analysis (TGA), were used to investigate the structure and properties of the as-prepared product. The results showed that the product was a grafted copolymer of CA and PLA, and PLA side chains were detected in t
