    Abstract: Blending of polyvinylchloride (PVC) and other rigid polymers may be facilitated using lubricant compositions comprising linear alpha olefins (LAOs) or compounds derived from LAOs. PVC blending methods may comprise: combining PVC and a lubricant composition to form a mixture, and blending the mixture to form a lubricated PVC blend, in which the mixture contains an effective amount of the lubricant composition to provide a fusion temperature for the lubricated PVC blend of about 190° C. or below as determined by torque rheometry at 65 rpm. The lubricant composition may comprise one or more C18+ linear alpha olefins (LAOs) having a kinematic viscosity of about 4 cSt or less at 135° C., or one or more LAO dimers formed from the one or more C18+ LAOs, the one or more LAO dimers having an internal olefin and a kinematic viscosity of about 6 cSt or less at 135° C., or reduced LAO dimers.

    Abstract: Disclosed herein are a variety of systems, compositions, and methods for reversibly storing electrical energy in a symmetric redox flow battery with a unit cell potential equal to or greater than 3 volts. The systems include a conjugated organic molecule, a positive section, and a negative section. The conjugated organic molecule comprises a pair of electron-donating groups and a pair of electron-withdrawing groups, wherein a first electron-donating group of the electron donating groups is one ring position from a first electron-withdrawing group of the electron-withdrawing groups, and wherein a second electron-donating group is one ring position from a second electron-withdrawing group of the electron-withdrawing groups. The positive section includes a first metal electrode in contact with a catholyte comprising a portion of the conjugated organic molecule. The negative section comprises a second metal electrode in contact with an anolyte including an additional portion of the conjugated organic molecule.
