POLYOLS DERIVED FROM FARNESENE FOR POLYURETHANES
A composition is provided for making a polyurethane that may be incorporated in various products, such as a sealant, a coating, a caulk, an electric potting compound, a membrane, a sponge, a foam, an adhesives, and a propellant binder. The composition includes one or more polyols, one or more isocyanate-group containing compounds having an isocyanate group functionality of at least two, and optionally one or more chain extenders. At least one of the polyols is a farnesene-based polyol having a number average molecular weight less than or equal to 100,000 g/mol and a viscosity at 25 C. less than 10,000 cP. The farnesene-based polyol may be a homopolymer or a copolymer of farnesene. The composition may also comprise additional polyols, such as a polyol of a homopolymer or copolymer of a polydiene. Methods of preparing a polyurethane are also provided.
Mutant polypeptides and uses thereof
The present disclosure provides novel polypeptides with 3-buten-2-ol dehydratase activity, polypeptides with catalytic activity in the conversion of 3-methyl-3-buten-2-ol to isoprene, and crystal structure data for one of such polypeptides. Methods of making and using the polypeptides and their related crystal structure data are also provided.

FARNESENE-BASED TACKIFYING RESINS AND ADHESIVE COMPOSITIONS CONTAINING THE SAME
A tackifying resin includes a farnesene-based polymer having monomeric units derived from a farnesene monomer and one or more optional comonomers selected from the group consisting of dienes, branched mono-olefins, and vinyl aromatics and has a softening point greater than or equal to 80 degrees Celsius. A method of making the farnesene-based polymer includes combining a farnesene monomer and a solvent and optionally adding one or more comonomers selected from the group consisting of dienes, branched mono-olefins, and 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. The tackifying resin may be combined with an elastomer to form a hot melt adhesive composition.
Uses of styrenic polymers derived through depolymerized polystyrene
A latex and solution with UV-active monomers created using styrenic polymers created via the depolymerization of a polystyrene feedstock. In some embodiments the polystyrene feedstock contains recycle polystyrene. In some embodiments, the styrenic polymers contain olefins. In some embodiments, the latex and solution with UV-active monomers are used in ink formulations. In some embodiments, latex and solution UV-active monomers can replace styrenated acrylics within flexo and/or gravure ink formulations. Other applications of the latex and solution with UV-active monomers can include, but are not limited to, coatings, paints, adhesives. Additional applications of the latex can include but are not limited to immunoassays.
