Due to the need of conserving petroleum resources

protection of the environment and developing concerns of economy

using renewable bio-based raw materials to replace petroleum derived polymeric materials have attracted great interest from scientists and the industry. Elastomer is a kind of material which is widely used in many fields. However

elastomers are mainly obtained from petroleum. Research on the development of bio-based elastomers is vital to cut down the use of petroleum and protect our environment. This article briefly introduces three kinds of bio-based elastomers—bio-based polyurethane elastomer

bio-based polyamide elastomer

bio-based polyester elastomer—which have received much more attention recently. It mainly focuses on the raw materials of the bio-based elastomer

synthetic routes and comparison between bio-based elastomers and the petroleum-based ones.
