POLYMERS INCLUDING A METHYLENE BETA-KETOESTER AND PRODUCTS FORMED THEREFROM
The present teachings are directed at 1,1-disubstituted alkene monomers (e.g., methylene beta-ketoester monomers), methods for producing the same, polymerizable compositions including a methylene beta-ketoester monomer, and polymers, compositions and products formed therefrom. The monomer preferably is a high purity monomer. In the method for producing the methylene beta-ketoesters of the invention, a beta-ketoester may be reacted with a source of formaldehyde. The methylene beta-ketoester monomers may be used in monomer-based products (e.g., inks, adhesives, coatings, sealants or reactive molding) and polymer-based products (e.g., fibers, films, sheets, medical polymers, composite polymers and surfactants).
SURFACE TREATMENT METHOD, ANTI-STATIC AGENT, AND HYDROPHILIZING TREATMENT AGENT
To provide a surface treatment method for hydrophilizing a surface of a treatment target and preventing charging by a simple and easy method and an anti-static agent. The present invention provides a surface treatment method. The method comprises an anti-static treatment step of coating a treatment target with an anti-static agent comprising an electrolyte (e1), a hydrophilic polymer (a) and water, and having electrical conductivity of 15 mS/m or more to obtain a coated film (A), drying the coated film (A) to obtain an anti-static layer, and a hydrophilizing treatment step of coating the anti-static layer with a hydrophilizing treatment agent comprising a hydrophilic polymer (b) and an alcohol to obtain a coated film (B), and drying the coated film (B), followed by rinsing thereof.

RESIN COMPOSITION AND METHOD OF FORMING RESIST PATTERN
A resin composition includes a resin A, a resin C, and a solvent. The resin A includes a sulfonic-acid-group-containing structural unit in an amount exceeding 5 mol % with respect to total structural units included in the resin A. The resin A has a content of a fluorine atom of 30 mass % or less with respect to a total mass of the resin A. The resin C includes a fluorine atom in a larger content per unit mass than the content of a fluorine atom per unit mass in the resin A. A content of the resin A in the resin composition is lower than a content of the resin C in the resin composition in terms of mass.
