Epoxidised Natural Rubber

Abstract

The main motivation for modification of natural rubber is to enhance its properties and expand its application in various rubber product sectors. There are two routes of modification which are viable with natural rubber, namely the physical and chemical. The latter involves reactions onto the unsaturated structure of natural rubber that result in changes to its structure. Amongst the chemically modified natural rubbers are hydrogenated and epoxidised natural rubbers. However, only epoxidised natural rubber (ENR) is of interest in the current publication. Various methods of epoxidation are available, and these include either a solution or latex environment but epoxidation via peracids method appears to be preferred due to better reaction rates and product purity. The epoxidation level in natural rubber can also be increased to 90%. However, 5 to 75% epoxidation level is a favoured range as it results in minimal secondary ring-opened structures such as trans-diol and five-membered cyclic ether.
