    Abstract: Solid-polymer electrolytes, methods of making solid-polymer electrolytes, and uses of solid-polymer electrolytes. A solid-polymer electrolyte comprises a cross-linked polymer network. A cross-linked polymer network may comprise a plurality of groups, which may be cross-linked groups, such as, for example, cross-linked difunctional polyether groups, cross-linked difunctional ionic groups, non-crosslinked groups, which may be referred to as “dangling” groups, or a combination thereof, and a plurality of cross-linked multifunctional crosslinker groups. A solid polymer electrolyte can be formed by polymerization. A solid polymer electrolyte can be formed in situ in a device. A solid polymer electrolyte can be used in devices such as, for example, batteries, supercapacitors, fuel cells, and the like.

    Abstract: Provided are compositions comprising isotactic polyethers. Methods of making isotactic polyethers, and uses thereof are also disclosed. Also provided are bimetallic complexes that can be used as catalyst. Methods of making isotactic polyethers and bimetallic complexes and uses thereof are also disclosed. For example, a racemic bimetallic (salalen)CrCl polymerization catalyst was prepared and used alkyl diol, PO-oligomer triols, and aPPO and PCL diols as CSAs in order to produce α,ω-hydroxy telechelic iPPO. These telechelic polymers have controlled molecular weights and are semicrystalline. Amorphous α,ω-hydroxy telechelic PPO can also be produced by increasing the reaction temperature in conjunction with the use of CSAs.
