“…In particular, natural rubber (NR) is a polymer composed of isoprene units linked to form double bonds with a cis configuration (99.9%, cis -1,4-polyisoprene) when extracted from the latex of the Hevea brasiliensis trees and Parthenium argentatum woody shrub [ 16 , 17 , 18 ]; trans configuration extracted from the latex of the Palaquium gutta trees ( trans -1,4-polyisoprene) [ 17 , 19 ]; and cis / trans isomer mixtures extracted from the latex of the Manilkara zapota trees [ 17 , 18 , 20 ]. NR (99.9%, cis -1,4-polyisoprene) is widely employed in the fabrication of tires, construction industries, and biomedical applications.…”

In 2021, global plastics production was 390.7 Mt; in 2022, it was 400.3 Mt, showing an increase of 2.4%, and this rising tendency will increase yearly. Of this data, less than 2% correspond to bio-based plastics. Currently, polymers, including elastomers, are non-recyclable and come from non-renewable sources. Additionally, most elastomers are thermosets, making them complex to recycle and reuse. It takes hundreds to thousands of years to decompose or biodegrade, contributing to plastic waste accumulation, nano and microplastic formation, and environmental pollution. Due to this, the synthesis of elastomers from natural and renewable resources has attracted the attention of researchers and industries. In this review paper, new methods and strategies are proposed for the preparation of bio-based elastomers. The main goals are the advances and improvements in the synthesis, properties, and applications of bio-based elastomers from natural and industrial rubbers, polyurethanes, polyesters, and polyethers, and an approach to their circular economy and sustainability. Olefin metathesis is proposed as a novel and sustainable method for the synthesis of bio-based elastomers, which allows for the depolymerization or degradation of rubbers with the use of essential oils, terpenes, fatty acids, and fatty alcohols from natural resources such as chain transfer agents (CTA) or donors of the terminal groups in the main chain, which allow for control of the molecular weights and functional groups, obtaining new compounds, oligomers, and bio-based elastomers with an added value for the application of new polymers and materials. This tendency contributes to the development of bio-based elastomers that can reduce carbon emissions, avoid cross-contamination from fossil fuels, and obtain a greener material with biodegradable and/or compostable behavior.

“…trees, also called gutta-percha and balata [8], respectively, synthesize the isomer with conformation trans-1,4. According to reports, the Manilkara zapota or chicle tree produces a 1/4 mixture of cis/trans polyisoprene [9] (Ch. 29-59, [10]).…”

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.

“…In this sense, it is worth to mention that blanching was effective in removing the waxy layer or latex sap present in the fruit surface, which interferes in the moisture transfer phenomena occurring during drying process (Reyes-Gómez et al, 2018;Xiao et al, 2017).…”
