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).

An undercoat agent including a block copolymer having a plurality of blocks bonded formed on a substrate. The undercoat agent contains a resin component that includes a structural unit having an aromatic ring and a structural unit having no aromatic ring, and the resin component includes a group which can interact with the substrate and does not include a 3 to 7-membered, ether-containing cyclic group; and a method of forming a pattern of a layer containing a block copolymer. The method includes applying an undercoat agent to a substrate to form a layer containing the undercoat agent; forming a layer containing a block copolymer having multiple blocks bonded on a surface of the layer containing the undercoat agent, followed by a phase separation of the layer containing the block copolymer; and selectively removing a phase containing at least one block of multiple blocks constituting the block copolymer.
