    • The invention features compositions and methods for producing polymers of isoprene derived from renewable resources such as isoprene produced from cultured cells that use renewable carbon sources. A starting isoprene composition, such as a bioisoprene composition, is distinguished from petroleum based isoprene by the purity profile (such as lower levels of certain C5 hydrocarbons other than isoprene, presence of certain compounds associated with the biological process for production) and the relative content of the carbon isotopes. Polymers obtained by polymerization of such starting isoprene composition according to this invention, such as a polyisoprene homopolymer or a copolymer having repeat units that are derived from isoprene, are distinguishable from isoprene containing polymers from petrochemical resources. The present invention more specifically discloses a polyisoprene polymer which is comprised of repeat units that are derived from isoprene monomer, wherein the polyisoprene polymer has d 13 C value of greater than -22‰. This type of polyisoprene can be a cis-1,4-polyisoprene homopolymer rubber. Also provided are methods for verifying that a polyisoprene homopolymer or a copolymer having repeat units that are derived from isoprene contains isoprene that is from a sustainable renewable non- petroleum derived source.
    • 本发明的特征是用于生产衍生自可再生资源的异戊二烯聚合物的组合物和方法,例如由使用可再生碳源的培养细胞产生的异戊二烯。 起始的异戊二烯组合物如生物异戊二烯组合物通过纯度分布(例如除异戊二烯以外的某些C5烃的较低水平,与生产生物过程相关的某些化合物的存在)以及相对含量 的碳同位素。 通过聚合本发明的这种起始异戊二烯组合物得到的聚合物,例如聚异戊二烯均聚物或具有衍生自异戊二烯的重复单元的共聚物,与来自石油化学资源的含异戊二烯聚合物是不同的。 本发明更具体地公开了由衍生自异戊二烯单体的重复单元组成的聚异戊二烯聚合物,其中聚异戊二烯聚合物的d13C值大于-220 / 00。 这种类型的聚异戊二烯可以是顺式-1,4-聚异戊二烯均聚物橡胶。 还提供了用于验证聚异戊二烯均聚物或具有衍生自异戊二烯的重复单元的共聚物含有来自可持续可再生非石油衍生源的异戊二烯的方法。
