A positive electrode for a battery includes a positive active material, a conductive agent, and a copolymer. The copolymer includes a constituent unit (a) represented by the following general formula (1) and a constituent unit (b) represented by the following general formula (2): (wherein R, R, R, R, R, Rand Rare the same or different and denote a hydrogen atom, a methyl group or an ethyl group, Rdenotes a hydrocarbon group having 8 to 30 carbon atoms, Rdenotes a linear or branched alkylene group having 2 to 4 carbon atoms, Xand Xdenote an oxygen atom or NH, and p denotes a number of 1 to 50).

Positive electrode for battery, and battery

The present invention provides a method for souring, using an scouring agent composition which has low-viscosity although being highly concentrated, which has excellent scouring property under highly alkaline conditions, and which has excellent biodegradability. That is, the present invention provides a method for scouring fiber, which comprises the step of treating the fiber with a scouring agent comprising (A) a nonionic surfactant having the formula (I):

Scouring agent composition for fiber

Biodegradable lubricating base oil, lubricating oil composition

A process for the preparation of a lubricating oil additive composition is described were an aromatic carboxylic ester is subjected to ring alkylation with an olefin, reacted with the oxide or hydroxide or an alcoholate of a divalent metal and carbon dioxide with the removal of formed water and/or an alcohol from the reaction mixture. A lubricating oil additive composition obtained by the process, and a lubricating oil composition containing the same is also described. The lubricating oil additive provides excellent oxidation stability, low susceptibility to carbonization and cleanability as compared with the conventional, commercially-available additives.
