Abstract: A hydrogenated styrenic block copolymer (HSBC) is disclosed represented by at least one formula selected from S-EP-EB, (S-EP-EB)nX, and S-EP-EB-EP-S, wherein n is from 2 to 30 and X is a residue of a coupling agent. Prior to hydrogenation, each block S is a polymer block of a vinyl aromatic monomer, each block EP is a polyisoprene block, and each block EB is a polybutadiene block. The HSBC has a polystyrene content (PSC) of 5 to 20 wt. %, and a peak molecular weight (Mp) of 45 to 300 kg/mol. A thermoplastic composition is disclosed containing the HSBC and a polyolefin. The thermoplastic composition shows improved impact performance and toughness.

Abstract: An electrode binder for use with rechargeable batteries is disclosed. In embodiments, the electrode binder comprises a styrenic block copolymer (SBC) for use with an electrode active material, such as Si, Si alloys, Si compounds, Si composites, carbon black, or graphite in an amount of at least 20 wt. %. The SBC can be unsaturated (USBC) or hydrogenated (HSBC), or functionalized, wherein functionality includes maleation, epoxidation, silanation, carboxylic acid/salt, quaternary ammonium salt, sulfonation and others. In embodiments, the electrode binder is selected from isoprene rubber (IR), silicone-containing block copolymer, and an electronically conductive block copolymer containing a block that is unhydrogenated CHD (cyclohexadiene) block.
