    摘要: A wellbore fluid contains a viscosifying polymer in which portions of the polymer are connected through formation of an inclusion complex involving cucurbituril 8 (i.e. CB[8]) as host molecule. The fluid contains guest molecules with first and second guest groups covalently attached wherein at least one of the guest molecules comprises a polymer chain. The CB [8] host and the guest molecules attach together through reception of first and second guest groups within CB[8] host cavities, thereby connecting polymer chains together as a larger, supramolecular polymer and enhancing viscosity of the fluid. Polymer molecules may be synthetic polymers and guest groups may be attached to monomers before polymerization. Alternatively guest groups may be attached to existing polymers which may be polysaccharide.

    摘要: A method is provided for synthesizing a polymer in a controlled fashion using a ring-opening metathesis polymerization (ROMP) reaction, wherein polymerization is carried out using a catalytically effective amount of an olefin metathesis catalyst and a bridged bicyclic or polycyclic olefin monomer that contains at least two heteroatoms directly or indirectly linked to each other. Preferred catalysts are Group 8 transition metal complexes, particularly complexes of Ru and Os. Such complexes include the ruthenium bisphosphine complex (PCy3)2(Cl)2Ru═CHPh (1) and the ruthenium carbene complex (IMesH2)(PCy3)(Cl)2Ru═CHPh (2). The invention also provides novel regioregular polymers synthesized using the aforementioned methodology, wherein the polymers may be saturated, unsaturated, protected, and/or telechelic. An exemplary polymer is poly((vinyl alcohol)2-alt-methylene)(MVOH).

    摘要: Disclosed herein are compositions of a deep eutectic solvent with a host, such as a supramolecular host, and the use of the composition to form a composition comprising the host in complex with one or more guests. The deep eutectic solvent provides an alternative medium to the aqueous-based media that have been used in the art to date. Also disclosed are compositions of a deep eutectic solvent with a redox-active compound, such as a viologen compound, and the use of the composition, for example, in a smart window or for agricultural use, such as in an agricultural product.
