The present disclosure provides a two-component solvent-less adhesive composition. The two-component solvent-less adhesive composition contains the reaction product of (A) an isocyanate component and (B) a polyol component containing a poly-ester-amide polycarbonate polyol. The present disclosure also provides a method of forming a two-component solvent-less adhesive composition.

A polyolefin-polydiorganosiloxane block copolymer may be prepared by Piers-Rubinsztajn reaction.

Polyolefin-polydiorganosiloxane block copolymer and method for the synthesis thereof

The present disclosure provides a two-component solvent-based adhesive composition. The two-component solvent-based adhesive composition contains the reaction product of (A) an isocyanate component; (B) a polyol component containing a polyester-amide polycarbonate polyol; and (C) a solvent. The present disclosure also provides a method of forming the two-component solvent-based adhesive composition.

A polyolefin-polydiorganosiloxane block copolymer may be prepared by hydrosilylation reaction.

Polyolefin-polydiorganosiloxane block copolymer and hydrosilylation reaction method for the synthesis thereof

Provided are new bottlebrush polymers and diblock bottlebrush copolymers, which can self-assemble into structures of desired morphology (e.g., hexagonal cylindrical, gyroid). The self-assembled structures of the bottlebrush polymers and copolymers provide useful materials such as photonics (e.g., photonic crystals), functional materials, chromatography media, stimuli-responsive materials, lubricants, nanolithography, films, and coatings. In certain embodiments, the backbone repeating units of the bottlebrush polymers and copolymers have two different polymeric sidechains covalently attached to the backbone repeating unit through a branched linker, wherein one of the polymeric sidechain is a polysiloxane. Also provided are methods of preparing the bottlebrush polymers and copolymers described herein.

Bottlebrush polymers and uses thereof

The disclosure provides nanostructures (e.g., nanospheres and nano-paddlewheels) formed through transition metal-ligand (e.g., Pd(II)-, Ni(II)-, or Fe(II)-ligand of Formula (A)) coordination and junction self-assembly. The disclosure also provides supramolecular complexes that include the nanostructures connected by divalent linkers Y. The provided supramolecular complexes are able to form gels (e.g., hydrogels). The gels are suprametallogels and exhibited excellent mechanical properties without sacrificing self-healing and showed high robustness and storage modulus. The present disclosure further provides compositions (e.g., gels) that include the nanostructures or supramolecular complexes and optionally an agent (e.g., small molecule), where the nanostructures and the nanostructure moieties of the supramolecular complexes may encapsulate and slowly release the agent. The nanostructures, supramolecular complex, and compositions may be useful in delivering an agent to a subject, tissue, or cell, as super-absorbent materials, and in treating a disease (e.g., a genetic diseases, proliferative disease (e.g., cancer or benign neoplasm), hematological disease, neurological disease, gastrointestinal disease (e.g., liver disease), spleen disease, respiratory disease (e.g., lung disease), painful condition, genitourinary disease, musculoskeletal condition, infectious disease, inflammatory disease, autoimmune disease, psychiatric disorder, or metabolic disorder).
