Abstract
Disclosed herein are rubber compositions comprising bio-oil produced by a recombinant cell. Also disclosed are methods of controlling the variability of fatty acid content in bio-oil containing rubber compositions or tires comprising at least one component incorporating the bio-oil containing rubber composition, and a method of providing a bio-oil-containing tire with a reduced carbon footprint.

1-19. (canceled)
A bio-oil-containing rubber composition, comprising
- 1 to 200 phr of bio-oil produced by a recombinant cell,
- at least one rubber including at least one diene monomer-containing polymer or copolymer,
- 5 to 200 phr of at least one reinforcing filler, and
- a cure package, wherein the at least one reinforcing filler comprises at least one of carbon black and silica and the amount of carbon black is no more than 30% by weight of the total amount of reinforcing filler.
A method for improving at least one of the wear rate or E′ of a rubber composition, the method comprising
- incorporating about 1 to about 200 phr of bio-oil produced by a recombinant cell into
- at least one rubber including at least one diene monomer-containing polymer or copolymer,
- 5 to 200 phr of at least one reinforcing filler, and
- a cure package,
- wherein the at least one reinforcing filler comprises at least one of carbon black and silica and the amount of carbon black is no more than 30% by weight of the total amount of reinforcing filler.
A method for controlling the variability of fatty acid content in a bio-oil-containing rubber composition, comprising
- incorporating about 1 to about 100 phr of bio-oil produced by a recombinant cell with
- at least one rubber including at least one diene monomer-containing polymer or copolymer,
- 5 to 200 phr of at least one reinforcing filler, and
- a cure package,
- thereby forming a bio-oil-containing rubber composition.
