    Abstract: There is provided a method for more easily producing an acrylic rubber capable of providing a crosslinked rubber having excellent water resistance. A method for producing an acrylic rubber comprising the steps of subjecting a monomer to emulsion polymerization to obtain a polymerized emulsion; mixing the polymerized emulsion with a coagulant to obtain a water-containing crumb; and water-washing the water-containing crumb, wherein, in the step of water-washing the water-containing crumb, the water-containing crumb is water-washed until an electrical conductivity of the washing water after water-washing the water-containing crumb becomes 6.0 mS/cm or less.

    Abstract: Provided is an electroconductive adhesive which is less apt to suffer cracking, chipping, etc. upon sintering and gives sintered objects having excellent mechanical strength. The electroconductive adhesive comprises metallic microparticles which include a protective layer comprising one or more amines and have an average particle diameter of 30-300 nm, the amines comprising a C5-7 monoalkylamine and/or an alkoxyamine represented by the following general formula (1). NH2—R2—O—R1 (1) In the protective layer, the ratio of the C5-7 monoalkylamine and/or alkoxyamine represented by the general formula (1) to one or more amines different therefrom is in the range of 100:0 to 10:90. [In formula (1), R1 represents a C1-4 alkyl group and R2 represents a C1-4 alkylene group.]

    Abstract: The objection of the present invention is to provide a photocurable resin composition having deep curability. The photocurable resin composition comprises an allyl polymer (a) produced by polymerization of an allyl compound represented by the following formula (1), a photocurable compound (b), and a photopolymerization initiator (c). In the formula, n represents an integer of 2 to 4; Z is selected from a binding site, an n-valent aliphatic chain hydrocarbon group optionally having a hydroxyl group, an n-valent alicyclic hydrocarbon group optionally having an alkyl group, and an n-valent aromatic hydrocarbon group optionally having an alkyl group; n is 2 and two —COOCH2CH═CH2 moieties are directly bonded to each other when Z is a binding site.

    Abstract: Provided is a binder for a battery electrode, the binder having superior binding properties and being capable of effectively decreasing the internal resistance of a battery while still being usable as an aqueous binder with low environmental burden. A binder for a battery electrode according to the present invention has a core shell structure of a core section (A) containing a copolymer the principal constituent of which is methyl methacrylate and a shell section (B) having a (meth)acrylate-based copolymer containing (meth)acrylate as a polymerization component, wherein the swelling ratios with respect to a mixed solvent in which ethylene carbonate and diethyl carbonate are mixed at a volume ratio of 3:7 are 10% or less for the resin constituting the core section (A) and 30% or more for the resin constituting the shell section (B).
