  • Patent number: 10658670
    Abstract: An anode includes a thin film of an anode material; and a protective layer that is formed on the thin film of the anode material, that is composed of functionalized metal oxide nanoparticles, which are lithium-terminated sulfonated metal oxide nanoparticles, and that has a thickness of 300-5000 nm. A method for manufacturing the anode includes dispersing the functionalized metal oxide nanoparticles into a dispersion medium to form a dispersion; dipping a substrate into water, and introducing the dispersion thereto so that the functionalized metal oxide nanoparticles form a self-assembled molecular film on the water surface; lifting the substrate over the water surface to transfer the self-assembled molecular film onto the substrate, thereby providing a substrate coated with a functionalized metal oxide film; and transferring the functionalized metal oxide film onto the thin film of the anode material to provide an anode coated with the functionalized metal oxide film.

  • Patent number: 4708994
    Abstract: This invention describes the preparation of reactive engineering thermoplastics containing arylcyclobutene groups pendant to an aromatic ring. The polymers are prepared by alkylation or acylation of an engineering thermoplastic which contains one or more aromatic groups capable of being alkylated or acylated with a suitable arylcyclobutene alkylating or acylating agent. The prepared reactive engineering thermoplastics containing pendant arylcyclobutene groups may be cross-linked and cured by heating above about 200.degree. C.

  • Patent number: 4351923
    Abstract: The invention relates to a process for preparing terpolymer polyblends having high gloss and ductility in formed articles, wherein, rubber particles in an aqueous latex are reacted with an alkenyl aromatic, alkenyl nitrile and alkyl acrylate monomer formulation such that said rubber particles become grafted with at least a portion of said monomers while said monomers form a matrix terpolymer phase of said monomers followed by separating said matrix phase terpolymer and said grafted rubber particles from said latex as a terpolymer polyblend. The invention also relates to a composition of said process.

  • Patent number: 4276394
    Abstract: Novel telechelic halogenated polymers of cationically polymerizable olefin monomers are formed carrying from 2 to about 6 terminal halogens. The telechelic halogenated polymers are formed by reacting the monomer with an initiator transfer agent, carrying at least two tertiary halogens, and under cationic polymerization conditions. Additionally, novel thermoplastic elastomer block copolymers are formed from these telechelic halogenated polymers by reacting the latter with vinyl aromatic monomers in the presence of a coinitiator.
