The present disclosure relates to a preparation method of an acrylate-based pressure-sensitive adhesive composition. According to the present disclosure, it is possible to provide a preparation method of an acrylate-based pressure-sensitive adhesive composition which exhibits high ball tack while suppressing the generation of bubbles due to its excellent antifoaming ability.

Preparation method of acrylate-based pressure-sensitive adhesive composition

The present invention relates to a binder composition for a secondary battery, an electrode slurry composition including the same, and an electrode and a secondary battery manufactured by using the same, the binder composition including: a latex particle (A) which is a polymer of a monomer mixture including (a1) a conjugated diene monomer, (a2) an ethylenically unsaturated carboxylic acid monomer, and (a3) an aromatic vinyl monomer; and an emulsifier (B), wherein the (a2) ethylenically unsaturated carboxylic acid monomer is included in an amount of 3 parts by weight or more based on 100 parts by weight of the monomer mixture and the emulsifier (B) is included in an amount of less than 3000 ppm based on 100 parts by weight of the latex particles.

Binder composition for secondary battery, and electrode slurry composition, electrode and secondary battery including same

Disclosed is a binder composition for secondary batteries including composite latex comprising conjugated diene latex particles (A) and copolymer latex particles (B), each present in an independent phase, wherein the composite latex has a pH of 7 or less.

Binder composition for secondary batteries, and electrode and lithium secondary battery including the same

A cyanoethyl group-containing polymer and a preparation method thereof are provided. The cyanoethyl group-containing polymer is characterized by having very low contents of functional groups other than cyanoethyl groups.

Cyanoethyl group-containing polymer and preparation method thereof

The present invention relates to a binder composition for a secondary battery, including: a copolymer having a functional group; and an alkali metal ion bound to the functional group of the copolymer or with which a constituent element of the functional group is substituted. The binder composition exhibits enhanced adhesive strength and also exhibits low resistance due to the alkali metal ion included in the copolymer, and thus may exhibit more stable electrochemical performance.
