Liquid epoxidised natural rubber (LENR) is a low molecular weight form of epoxidised natural rubber (ENR) which was prepared via degradation of the said rubber in latex stage with redox reagent as degrading agents. The chemical behaviour of ENR latex as a starting material and LENR as a product upon storage were studied. The number average molecular weight (M_n), weight average of molecular weight (M_w), gel content and epoxidation level of ENR latex were consistent as the storage time increased. This indicated that the ENR latex was stable and suitable to be used up to six months of storage as the starting material for LENR preparation. The molecular weight of LENR prepared in reactor scale (LENR B) decreased by 24% from LENR A which prepared in laboratory scale. There were slight changes in the ring opening which was confirmed by nuclear magnetic resonance (NMR) and Fourier transform infrared (FTIR) spectroscopy. It was observed the properties of LENR such as molecular weight, epoxidation level, epoxy derivatives and gel content were almost consistent for one year of storage at room temperature.

液态环氧化天然橡胶 (LENR) 是一种低分子量形式的环氧化天然橡胶 (ENR)，它是通过在胶乳阶段用氧化还原试剂作为降解剂降解所述橡胶而制备的。研究了作为起始材料的 ENR 胶乳和作为产品的 LENR 在储存时的化学行为。数均分子量（M _n），重均分子量（M _w)，随着储存时间的增加，ENR 胶乳的凝胶含量和环氧化水平是一致的。这表明 ENR 胶乳是稳定的，适合用作 LENR 制备的起始材料长达六个月的储存。以反应器规模制备的 LENR (LENR B) 的分子量比以实验室规模制备的 LENR A 降低了 24%。核磁共振（NMR）和傅里叶变换红外（FTIR）光谱证实了开环的轻微变化。观察到 LENR 的性质，如分子量、环氧化水平、环氧衍生物和凝胶含量，在室温下储存一年后几乎一致。
