Internal Polymerization of Epoxy Group of Epoxidized Natural Rubber by Ferric Chloride and Formation of Strong Network Structure
In this work, studies are carried out to understand the crosslinking reaction of epoxidized natural rubber (50 mol% epoxy, ENR-50) by metal ion namely ferric ion (Fe<sup>3+</sup>, FeCl<sub>3</sub>, ferric chloride). It is found that a small amount of FeCl<sub>3</sub&...

| description | In this work, studies are carried out to understand the crosslinking reaction of epoxidized natural rubber (50 mol% epoxy, ENR-50) by metal ion namely ferric ion (Fe<sup>3+</sup>, FeCl<sub>3</sub>, ferric chloride). It is found that a small amount of FeCl<sub>3</sub> can cure ENR to a considerable extent. A direct interaction of the ferric ion with the epoxy group as well as internal polymerization enable the ENR to be cured in an efficient manner. It was also found that with the increased concentration of FeCl<sub>3</sub>, the crosslinking density of the matrix increased and therefore, the ENR offers higher mechanical properties (i.e., modulus and tensile strength). In addition, the glass transition temperature (<i>t<sub>g</sub></i>) of ENR vulcanizate is increased with increasing concentration of FeCl<sub>3</sub>. Moreover, the thermal degradation temperature (T<sub>d</sub>) of the ENR-FeCl<sub>3</sub> compound was shifted toward higher temperature as increasing concentration FeCl<sub>3</sub>. |
