摘要： Provided is a binder for a nonaqueous electrolyte secondary battery electrode. The binder contains a crosslinked polymer having a carboxyl group, or salt thereof, a use therefor, and a method for manufacturing a carboxyl group-containing crosslinked polymer or salt thereof for use in the binder. The crosslinked polymer contains a structural unit derived from an ethylenically unsaturated carboxylic acid monomer in the amount of 50 to 100 mass % of total structural units, and after the crosslinked polymer neutralized to a degree of a neutralization of 80 to 100 mol % has been subjected to water swelling in water and then dispersed in a 1 mass % NaCl aqueous solution, the particle diameter thereof is 0.1 to 7.0 μm in a volume-based median diameter.

摘要： The present invention is a method for producing a polysiloxane represented by formula (1), which includes a condensation step wherein a hydrolysis/polycondenzation of a starting material monomer that forms a constituent unit is carried out in a reaction solvent that contains at least one alcohol that is selected from among secondary alcohols having 4-6 carbon atoms and tertiary alcohols having 4-6 carbon atoms. The method for producing a polysiloxane of the present invention suppresses problems such as gelation that occurs during the production, and increase in the molecular weight or gelation that occurs during storage after the production or the like.
