Polyisoprene is a polymer formed from isoprene monomers. It is a naturally occurring elastomer, with cis-1,4-polyisoprene being the primary component of natural rubber. This natural form is produced by various plants, most notably the rubber tree (Hevea brasiliensis). Synthetic polyisoprene can also be manufactured through polymerization of isoprene monomers. The properties of polyisoprene, whether natural or synthetic, include high elasticity, resilience, and tensile strength. It is known for its ability to stretch significantly and return to its original shape.

Polyisoprene finds extensive use in a wide range of applications due to its unique properties. Natural rubber, a form of polyisoprene, is historically significant and has been utilized for centuries. In modern times, both natural and synthetic polyisoprene are critical materials in the manufacturing of tires, gloves, balloons, adhesives, footwear, and various industrial components. The specific isomer of polyisoprene, such as cis or trans, influences its physical characteristics and therefore its suitability for different uses. For instance, cis-1,4-polyisoprene is predominantly used in applications requiring high elasticity, while trans-1,4-polyisoprene, also found in gutta-percha, has different mechanical properties. The processing of polyisoprene often involves vulcanization, a chemical process that improves its strength and elasticity by forming cross-links between polymer chains.
