Provided herein are aqueous dispersions. The aqueous dispersions can comprise a first copolymer derived from one or more ethylenically unsaturated monomers, and a second carboxy-functional copolymer derived from one or more carboxylic acid-containing monomers. The aqueous dispersions can be used to prepare low- or zero-VOC aqueous coating compositions that possess desirable properties, including good block resistance and scrub resistance. Coatings and coating formulations comprising the aqueous dispersion, as well as methods of making and using the same are also provided.

The present invention provides a polymerizable composition containing a specific polymerizable compound and a fluorosurfactant having a specific polyoxyalkylene skeleton and having specific molecular weight. The invention also provides an optically anisotropic body, a retardation film, an antireflective film, and a liquid crystal display device that are produced using the polymerizable composition of the present invention. The present invention is useful because, when an optically anisotropic body is produced by photo-polymerization of the polymerizable composition, three features including the leveling properties of the surface of the optically anisotropic body, offset onto the substrate, and liquid crystal alignment can be improved simultaneously.

There is described an acrylic polyester resin, obtainable by grafting an acrylic polymer with a polyester material. The polyester material is obtainable by polymerizing (i) a polyacid component, with (ii) a polyol component. At least one of the polyacid component and/or the polyol component comprises a monomer having an aliphatic group containing at least 15 carbon atoms. At least one of the polyacid component and/or the polyol component comprises a functional monomer operable to impart functionality on to the polyester resin, such that an acrylic polymer may be grafted with the polyester material via the use of said functionality. Also provided is an aqueous coating composition comprising the acrylic polyester resin and a packaging coated with the composition.

Provided is a graft copolymer and a treatment method which give excellent antifouling property to a substrate, especially a carpet. The graft copolymer has a trunk polymer having a hydroxyl group; and a branch having a C.sub.7-40 hydrocarbon group bonded to the trunk polymer at a carbon atom substituted with the hydroxyl group, wherein the branch has a repeating unit formed from an acrylic monomer represented by the formula: CH.sub.2═C(—X)—C(═O)—Y.sup.1—Z(—Y.sup.2—R).sub.n. The treatment method include applying the graft copolymer to the substrate.

Multiphase polymers comprising crosslinking monomers and polyfunctional amine are disclosed. The multiphase polymer comprises a first phase polymer having a Tg from 60° C. to 240° C., a second phase polymer having a Tg from 40° C. to 240° C., and a soft phase polymer having a Tg from -25° C. to 30° C. The crosslinking monomers include a triacrylate such as trimethylol propane triacrylate, an unsaturated alkoxysilane, and an unsaturated keto monomer reactive with the polyfunctional amine. In contrast to conventional knowledge, incorporation of trimethylolpropane triacrylate reduces the minimum film forming temperature of multiphase polymers. This unusual reduction in MFFT helps to reduce the VOC requirement to form a good film at low VOC. The other crosslinking monomers including unsaturated alkoxy silane and unsaturated keto monomer which react with the polyfunctional amine improve print resistance, block resistance and lower the tackiness of paint films. The multiphase polymer is particularly suitable for use in deep base paints.

A polymer for an electrode protective layer including a polymer (A) including a fluorine-based polymer in which a monomer unit including poly(alkylene oxide) and a monomer unit including a curable functional group (e.g., a thermocurable functional group or a photocurable functional group) are grafted on the fluorine-based polymer, and when preparing an electrode by coating an electrode active material layer using the polymer and curing (e.g., thermally curing or photocuring) the result, excellent lithium ion conductivity is obtained since lithium ion flow is not inhibited, chemical resistance for an electrolyte liquid is high, and voltage stability of a secondary battery may be enhanced by suppressing side reactions with the electrolyte liquid occurring on an electrode active material surface due to properties of a uniform and flexible protective layer.

Described herein is method of functionalizing fluorinated polymers, wherein a reaction compound is grafted onto a fluorinated polymer, wherein the fluorinated polymer comprises at least one Br, I, and Cl group and is free of —CH.sub.2CH.sub.2— linkages.

Such functionalized fluorinated polymers may be used in coating compositions.
