Description |
Polyisoprene is strictly a general term for polymers produced by the polymerization of isoprene. In practice, polyisoprene is commonly used to refer to synthetic cis-1,4-polyisoprene made by the industrial polymerization of isoprene. Natural forms of polyisoprene are also used in large quantities, most importantly "natural rubber" (mainly cis-1,4-polyisoprene) extracted from tree sap. Both synthetic polyisoprene and natural rubber are highly elastic, so they can be used to make tires and a variety of other applications. |
Application |
Natural rubber and synthetic polyisoprene are mainly used in tires. Other applications include latex products, footwear, belts, hoses and condoms. Natural gutta-percha and synthetic trans-1,4-polyisoprene for golf balls. |
Features And Benefits |
The trans isomer is more difficult than the cis isomer and has also had important uses in the past. |
