    Abstract: This invention relates to 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 its 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.

    Abstract: The invention produces suspensions of higher ?-olefins without using cryogenic comminution as well as without using polymer precipitation by adding a non-solvent to a polymer solution. Fine polymer dispersions are produced by thermal re-precipitation of a polymer in a liquid being a non-solvent for that polymer at room temperature and being capable of dissolving the polymer at a higher temperature. The polymer component of a suspension is produced by co-polymerization of higher ?-olefins in a monomer mass in the presence of a Ziegler-Natta catalyst.
