摘要：
Liquid natural rubber (LNR) was synthesized via photosentisized degradation of natural rubber (NR). LNR was modified into epoxidized liquid natural rubber (LENR) and hydroxylated liquid natural rubber (LNR-OH) using Na2WO4/CH3COOH/H2O2 catalytic system. Chemical structures of LNR and modified LNRs were characterized using Attenuated Total Reflectance Fourier Transform Infrared (ATR-FTIR) and H-1 Nuclear Magnetic Resonance (NMR) spectroscopies. Integration of H-1 NMR was used to calculate the epoxy content (%) of LENR. H-1 NMR detected the formation of LNR-OH after prolonged heating and increased of catalyst in oxidation reaction.
