Farnesene resins, rubber compositions, and tire compositions

摘要

A farnesene polymer is provided having a glass transition temperature greater than zero degrees Celsius that is obtained by combining a farnesene monomer and a solvent and optionally adding one or more vinyl aromatic comonomers to provide a monomer feed and polymerizing the monomer feed with a Friedel-Crafts catalyst. The farnesene polymer may be included as a resin in a rubber composition for tire applications.

1. A rubber composition comprising at least one elastomer selected from synthetic and natural elastomers, a filler, and a farnesene polymer having a To greater than zero degrees Celsius,
the farnesene polymer made according to a method comprising combining a farnesene monomer and a solvent and optionally adding one or more comonomers selected from the group consisting of vinyl aromatics, to provide a monomer feed, and polymerizing the monomer feed by combining the monomer feed with a Friedel-Crafts catalyst in a vessel.
