摘要：Problem: even if the aqueous solution of a copolymer of a vinyl alcohol and analkali metal neutralizer of an ethylenically unsaturated carboxylic acid or an aqueoussolution of carboxymethylcellulose or its salt is stored in an aqueous solution state, asignificant thickening is performed Find a technique that can be used as a binder forsecondary batteries. Solution Copolymer of vinyl alcohol and ethylenically unsaturatedcarboxylic acid alkali metal neutralizer or aqueous composition of carboxymethylcellulose or salt thereof Under the room temperature (25 ° C.), the composition wasdiluted with water (25 ° C. or less) so that the viscosity was 200 ± 100 MPa · s, the

composition temperature was adjusted to 25.degree. C., the composition viscosity was setto XA1 (Pa. s), and the composition was placed in a closed container and kept stationaryfor When the composition viscosity is xb1 A composition whose rate of change is 0 to 10%determined by the following formula. Change rate (%) = (XA1 xb1) \\/ xb1 x 100 Noselection
