  • ADDITIVE, SURFACE TREATMENT AGENT, SURFACE-MODIFIED LATEX PARTICLES, METHOD FOR PRODUCING SURFACE-MODIFIED LATEX PARTICLES, REAGENT FOR LATEX AGGLUTINATION REACTION, KIT, AND METHOD FOR DETECTING TARGET SUBSTANCE
    Publication number: 20220380503
    Abstract: Provided are an additive and a surface treatment agent capable of suppressing agglutination of latex particles contained in a reagent for a latex agglutination reaction during storage of the reagent although a synthetic polymer is contained as an active component. An additive is to be added to latex particles used in a reagent for a latex agglutination reaction. The latex particles have not been subjected to blocking treatment. The additive includes a polymer containing more than 60% by mass and 99% by mass or less of hydrophilic repeating units (A) relative to all repeating units and 1% by mass or more and less than 40% by mass of hydrophobic repeating units (B) relative to all repeating units, and having a weight average molecular weight of 3,000 or more.

  • Binder composition for electrical storage device electrodes, slurry for electrical storage device electrodes, electrical storage device electrode, and electrical storage device
    Patent number: 9583278
    Abstract: An electrical storage device electrode binder composition containing a polymer (A) and a liquid medium (B). A repeating unit (A4) derived from an unsaturated carboxylic acid compound is included in the polymer (A) in an amount of 5-40 parts by mass based on 100 parts by mass of the total repeating units in polymer (A). The polymer (A) is in particle form, and the polymer particles have a surface acid content of 1-6 mmol/g.
