Preparation and Characterization of Epoxidized Natural Rubber

Abstract

Epoxidized Natural Rubber is prepared with latex processing technology. The relationships of the epoxidation with the reaction times and temperature were investigated. The structure of ENR was characterized by Fourier transform-infrared spectroscopy (FIIR). It is found that, the by products, ring-open components increases with the reaction temperatures and the reaction times. It is found that as the level of epoxidation increased, the number of tetrahydrofuran ring increased.

Thermal Stability and Rheological Properties of Epoxidized Natural Rubber-Based Magnetorheological Elastomer

“…Therefore, epoxidized natural rubber (ENR) was chosen in this study since it is well-known as an environmentally-friendly or green material made of the natural resource corresponding to natural rubber (NR) [2,32,33,34,35,36]. Fundamentally, the ENR is synthesized by modifying NR latex via an epoxidation process.…”

“…Through this process, the compatibility with polar polymers, wear, thermal, and mechanical properties are improved [36]. Furthermore, as a new rubber, the ENR not only has better properties than NR such as high thermal resistance but some features of synthetic rubber could be attained [33,34,36,37,38]. The ENR has been commercialized as a ‘green tyre’ [38,39].…”

Optimization of the process of obtaining epoxidized natural rubber for the development of new composite materials on its basis

“…It is found that, using the technology of processing latex of nanocrystals, open-ring components increase with the reaction temperature and reaction time. It has been established that as the degree of epoxidation increases, the number of tetrahydrofuran rings increases [6].…”

Supertoughened Biobased Poly(lactic acid)–Epoxidized Natural Rubber Thermoplastic Vulcanizates: Fabrication, Co-continuous Phase Structure, Interfacial in Situ Compatibilization, and Toughening Mechanism

“…Chumeka et al, Jaratrotkamjorn et al, and Juntuek et al incorporated compatibilizers of NR- g -(vinyl acetate) (VA), NR- g -(methyl methacrylate) (MMA), and NR- g -(glycidyl methacrylate) (GMA) into PLA/NR blends, respectively. Epoxidized natural rubber (ENR), derived from natural rubber latex after being treated with peroxide, has better compatibility with PLA. However, there are only a few examples of literature − reported using ENR to modify PLA.…”
