Abstract: Provided herein are polyfarnesenes such as farnesene homopolymers derived from a farnesene and farnesene interpolymers derived from a farnesene and at least a vinyl monomer; and the processes of making and using the polyfarnesenes. The farnesene homopolymer can be prepared by polymerizing the farnesene in the presence of a catalyst. In some embodiments, the farnesene is prepared from a sugar by using a microorganism.

Abstract: Provided herein are drilling fluids comprising microbial-derived bio-organic compounds, a weighting agent and a viscosifier. In some embodiments, the microbial-derived bio-organic compounds comprise a famesane, a farnesene or a combination thereof. In certain embodiments, the drilling fluid comprises a continuous phase comprising a famesane, a farnesene or a combination thereof; and a discontinuous phase comprising water or an aqueous solution, an emulsifier, a weighting agent and a viscosifier. In other embodiments, the viscosifier is an organophillic clay.

Abstract: Provided herein are polyfarnesenes derived from a farnesene and at least two different vinyl monomers. Also provided herein are polyfarnesenes derived from a farnesene; at least two different vinyl monomers, such as (meth)acrylic acid, (meth)acrylic esters, styrene, and substituted styrenes; and at least one functional comonomer such as maleic anhydride.

Abstract: An improved thickening composition for aqueous systems including latex paints and coatings is described. The substantially anhydrous composition comprises in specified ratios a solid thickener polymer, and one or more surfactants. The solid thickener polymer includes associative thickeners. Associative thickener polymers include polyurethanes, polyesters, polyacrylamides, modified hydroxyethyl celluloses, alkali soluble emulsions and other chemicals. Specific surfactants utilized include dialkyl sulfosuccinates, alkyl sulfates, alpha olefin sulfonates and sulfates of ethoxylated alcohols.
