Abstract

Abstract: Biomass-based thermoplastic elastomer materials derived from cellulose, furfural and grease were prepared by "graft from" ATRP using ethyl cellulose(EC), tetrahydrofurfuryl methacrylate(THFMA) and lauryl methacrylate(LMA). FT-IR, ¹H NMR and GPC were applied to characterize the structure of graft copolymers, and proved the successful preparation of graft copolymer. The DSC analysis showed that the T_g of EC graft copolymers were between 13℃ and 27℃. The mechanical properties test showed that the tensile strength increased from 5.1 MPa to 13.7 MPa with the increasing of THFMA content in the feed. Compared to the linear copolymer which has the same THFMA/LMA composition, the EC graft copolymer possessed 3.7 times higher tensile strength. It is worth noting that the EC content in the feeding is between 0.91%-1.42%, which indicated that a small amount of EC could greatly improve the mechanical properties of graft copolymer.

Key words: ATRP, ethyl cellulose(EC), thermoplastic elastomer, characterization
