Abstract
Provided is an eucommia-derived biopolymer, which is obtained by biologically decaying an eucommia to obtain an eucommia decomposition product, and washing the eucommia decomposition product. The biopolymer is obtained by such a convenient method, and contains mainly a trans-isoprenoid and has a relatively high molecular weight. Therefore, the biopolymer is solid and elastomeric, and is useful as an industrial material.
