    Liquid natural rubber (LNR) was functionalized into liquid epoxidized natural rubber (LENR) and hydroxylated LNR (LNROH)
    via oxidation using a Na2
    WO4
    /CH3
    COOH/H2
    O2
    catalytic system. Microstructures of LNR and functionalized LNRs
    were characterized using Fourier Transform Infrared (FTIR) and Nuclear Magnetic Resonance (NMR) spectroscopies. The
    effect of CH3
    COOH, H2
    O2
    , Na2
    WO4
    , reaction time and temperature. reaction time and temperature on epoxy content were
    investigated. LNR-OH was obtained when oxidation reaction was conducted at a longer reaction time, higher temperature
    or excess amount of catalyst. Thermogravimetric analysis (TGA) reported the thermal behavior of functionalized LNRs.
    Molecular weight and polydispersity index (PDI) were determined using gel permeation chromatography (GPC).
