Abstract: A binder resin composition for secondary battery electrodes is described as containing a polymer (A) that has a structural unit represented by general formula (1) and a water-insoluble particulate polymer (B-1) and/or a water-soluble polymer (B-2) where (A), (B-1) and (B-2) are defined as described. A slurry for secondary battery electrodes contains the binder resin composition, an active material and a solvent. An electrode for secondary batteries is provided with a collector and an electrode layer that is arranged on the collector, where the electrode layer contains an active material and the binder resin composition. Alternatively, the electrode layer is obtained by applying the slurry for secondary battery electrodes to the collector, and drying the slurry thereon.

Abstract: Disclosed is a production method of a thermoplastic resin composition which has a good light emission property of visible light by ultraviolet irradiation, the production method comprising: compounding 0.001 to 50 parts by mass of at least one of metal compound (B) selected from a metal complex (B1) and a metal halide (B2), and 0.001 to 30 parts by mass of a polyalkylene glycol compound (C), with respect to 100 parts by mass of a thermoplastic resin (A); and heating it at a temperature of 100 to 320° C.

Abstract: A binder resin for a nonaqueous secondary battery electrode of the invention satisfies Is?30 (Is indicates a sum of scattering intensities observed in a particle size range of from 1 to 100 nm) when a solution is formed by dissolving the binder resin in water at a concentration of 5% by mass and particle size distribution is measured by a dynamic light scattering method at 25° C. The binder resin contains a polymer (B) having a structural unit represented by the following Formula (11) and a specific structural unit. The binder resin also contains a polymer (?) having a specific structural unit and a structural unit represented by the following Formula (22), and/or a mixture of a polymer (?1) having a specific structural unit and a polymer (?2) having a structural unit represented by the following Formula (22).

Abstract: A modifier for polyvinylidene fluoride (PVDF), which improves the adhesion of PVDF to a metal, a binder resin composition for battery and a battery using the PVDF modifier are provided. The modifier for polyvinylidene fluoride herein is a modifier in which the peeling strength of a specific cured film to an aluminium foil is 20 g/cm or more, and the specific cured film is obtained from a mixture of 6 parts by mass of the modifier for polyvinylidene fluoride and 14 parts by mass of a polyvinylidene fluoride composition. The modifier preferably contains a macromonomer copolymer (X), obtained by polymerizing both a macromonomer (A) having unsaturated double bonds and a vinyl monomer (B) having polar groups. The macromonomer (A) is preferably a methacrylic acid ester-based macromonomer (A-1). The vinyl monomer (B) is preferably a methacrylate, and a fluoroalkyl methacrylate.

Abstract: Disclosed is a process for the preparation of a poly-(meth)acrylate ester, which comprises, upon polymerization of a (meth)acrylate ester by using an organometallic compound ((C.sub.5 Me.sub.5).sub.2 SmMe(thf) or the like) having at least one polymerization initiating site, carrying out the polymerization in the presence of a compound (acetophenone, 4-methyl-2-pentanone or the like), which contains in the molecule thereof a reactive hydrogen atom, as a chain transfer agent. The above-described process makes it possible to control the molecular weight easily, reduce the using amount of the organometallic compound, prevent the coloring of the poly(meth)acrylate ester and improve thermal decomposition resistance.
