摘要

A binder resin for a nonaqueous secondary battery electrode, said binder resin satisfying the requirement IS>=30 (wherein IS stands for the sum of scattering intensities measured within a particle diameter range of 1-100 nm) when dissolved in water to give a solution having a concentration of 5 mass% and then subjected to particle size distribution measurement by the dynamic light scattering method at 25oC. The binder resin for a nonaqueous secondary battery electrode according to the present invention comprises a polymer (B) that has a structural unit represented by general formula (11) and a specific structural unit. The binder resin for a nonaqueous secondary battery electrode according to the present invention comprises a polymer (alpha) that has a specific structural unit and a structural unit represented by general formula (22), and/or a mixture of a polymer (beta1) that has a specific structural unit with a polymer (beta2) that has a structural unit represented by general formula (22).
