N2 - An oxyethylene chain (-CH 2-CH 2-O-) grafted polymer (P(MMA-MAh)-PEGME) was synthesized by reacting poly(ethylene glycol) monomethyl ether (PEGME) with the copolymer of poly(methyl metacrylate-maleic anhydride) (P(MMA-MAh)) and endcapping the residual carboxylic acid with methanol. Rectorite modified with dodecyl benzyl dimethyl ammonium chloride (OREC) was used as a filler additive to modify gel polymer electrolytes (GPE) that consisted of P(MMA-MAh)-PEGME used as polymer matrix, propylene carbonate (PC) as plasticizer and LiClO 4 as lithium ion producer. Characterization of interaction of the polar group of C=O or C-O-C in PC and grafted polymer with Li + and OH group on OREC surface has been thoroughly examined using Fourier transform infrared (FTIR), respectively. The quantitative analysis of FTIR shows that the absorptivity coefficients (a) of polymer/LiClO 4, PC/LiClO 4, PC/OREC and polymer/OREC are 0. 705, 0. 113, 0. 430 and 0. 500, respectively, which means that the Li + or OH bonded polar group of C=O and C-O-C is more sensitive than free C=O and C-O-C in FTIR spectra. The limited values of bonded C=O and C-O-C equivalent fraction of polymer/LiClO 4, PC/LiClO 4, PC/OREC and polymer/OREC are 33%, 94%, 60% and 22%, respectively, which implies that the interaction within the components is reversible and the intensity of interaction is ordered as PC/LiClO 4, PC/OREC, polymer/OREC and polymer/LiClO 4.
