“…However, IR nanocomposites can fully mimic the mechanical properties of NR [4], which is fundamental for specific applications. In spite of differences in mechanical properties, IR can replace its naturally occurring counterpart [29] in most industrial applications. IR high cis-1,4 (98%, predominantly head-tail linkages) exhibits many good properties, such as NR (high resilience, strength, and abrasion resistance), and both can be used with water, polar organic solvents (organic acids, alcohols, ketones), and some dilute acids and alkalis.…”

“…Prepared from the isoprene monomer, Bouchardat reported in 1879 the first production of a "synthetic rubbery material" using hydrochloric acid. This work quickly triggered research for a new synthetic route capable of transforming isoprene into a useful rubber [29].…”

“…Great interest has been focused on synthetic routes with high cis-1,4-polyisoprene content (above 90%) since the demand in the application fields keeps growing. Despite catalyst systems based on alkyl-lithium being able to produce as much as 98% of cis-1,4-polyisoprene in ideal conditions, commercially they produce 91% of cis-1,4and 9% of 3,4-polyisoprene (this catalytic system is only used by Kraton company to synthesize isoprene rubber under the name of Cariflex ® ) [12,29,50,54].…”

Up to now, rubber materials have been used in a wide range of applications, from automotive parts to special-design engineering pieces, as well as in the pharmaceutical, food, electronics, and military industries, among others. Since the discovery of the vulcanization of natural rubber (NR) in 1838, the continuous demand for this material has intensified the quest for a synthetic substitute with similar properties. In this regard, synthetic polyisoprene rubber (IR) emerged as an attractive alternative. However, despite the efforts made, some properties of natural rubber have been difficult to match (i.e., superior mechanical properties) due not only to its high content of cis-1,4-polyisoprene but also because its structure is considered a naturally occurring nanocomposite. In this sense, cutting-edge research has proposed the synthesis of nanocomposites with synthetic rubber, obtaining the same properties as natural rubber. This review focuses on the synthesis, structure, and properties of natural and synthetic rubber, with a special interest in the synthesis of IR nanocomposites, giving the reader a comprehensive reference on how to achieve a mimic of NR.
