The present disclosure describes functional oligomers or functional polymers. The functional oligomers or functional polymers may contain functional groups, e.g., —OH and/or —CHO. The functional oligomers or functional polymers may be obtained from hydrolyzing certain copolymers and may be soluble in commercially available solvents. The copolymers may be thermosetting polymers. The functional oligomers and functional polymers may be useful for recycling thermosetting polymers and may be useful as starting materials for preparing additional oligomers or polymers.

Functional oligomers and functional polymers including hydroxylated polymers and conjugates thereof and uses thereof

A class of sulfonimide salts for solid-state electrolytes can be synthesized based on successive SAr reactions of fluorinated phenyl sulfonimides: Fluorinated Aryl Sulfonimide Tags (FAST). The chemical and electrochemical oxidative stability of these FAST salts as well as other properties like solubility, Lewis basicity, and conductivity can be tuned by introducing different numbers and types of nucleophilic functional groups to the FAST salt scaffold.

Sulfonimide salts for battery applications

The present disclosure provides cyclic silyl ethers of the formula: and salts thereof. The cyclic silyl ethers may be useful as monomers for preparing polymers. Also described herein are polymers prepared by polymerizing a cyclic silyl ether and optionally one or more additional monomers. The polymers may be degradable (e.g., biodegradable). One or more O—Si bonds of the polymers may be the degradation sites. Also described herein are compositions and kits including the cyclic silyl ethers or polymers; methods of preparing the polymers; and methods of using the polymers, compositions, and kits.

Degradable polymers of a cyclic silyl ether and uses thereof

The present invention provides polymers and methods of preparing the same. In certain embodiments, the polymers comprise acrylate repeating units that have been derivatized (e.g., reduced and/or substituted) to form new polymeric structures. In certain embodiments, the polymers described herein self-assemble to form well-defined nanostructures. In some instances, the nanostructures exhibit relatively small d-spacing (e.g., a d-spacing value of 10 nm or less). Due to their properties, the polymers described herein are useful in a variety of applications including functional materials and biomedical applications.

Polymers and uses thereof

A metal-oxygen battery can provide improved energy storage and transportation applications due to high gravimetric energies, and such a metal-oxygen battery can include a polyolefin including a plurality of functional groups such as sulfamide, sulfoxy, carbonyl, phosphoramide or heterocyclic groups.
