  • Patent number: 11214665
    Abstract: A polymerization initiator composition includes isomers of the polymerization initiator, thereby preventing instability and inertness of the polymerization initiator and physical property degradation of the SSBR, minimizing by-products and unreacted materials, and remarkably improving a conversion ratio. In addition, when the polymerization initiator composition according to the present invention is used, there is no need to add a polar additive separately upon polymer polymerization, since the polar additive is already added at the time of preparing the polymerization initiator. Further, the polymer initiator composition has high polarity so that the hydrophobic SSBR and the hydrophilic silica can be effectively dispersed.

  • Patent number: 11207672
    Abstract: The anion exchange membranes exhibit enhanced chemical stability and ion conductivity when compared with traditional styrene-based alkaline anion exchange membranes. A copolymer backbone is polymerized from a reaction medium that includes a diphenylalkylene and an alkadiene. The copolymer includes a plurality of pendant phenyl groups. The diphenyl groups on the polymer backbone are functionalized with one or more haloalkylated precursor substrates. The terminal halide from the precursor substrate can then be substituted with a desired ionic group. The diphenylethylene-based alkaline anion exchange membranes lack the ?-hydrogens sharing tertiary carbons with phenyl groups from polystyrene or styrene-based precursor polymers, resulting in higher chemical stability. The ionic groups are also apart from each other by about 3 to 6 carbons in the polymer backbone, enhancing ion conductivity. These membrane are advantageous for use in fuel cells, electrolyzers employing hydrogen, ion separations, etc.
