Abstract: A binder resin for a nonaqueous secondary battery electrode of the invention satisfies Is?30 (Is indicates a sum of scattering intensities observed in a particle size range of from 1 to 100 nm) when a solution is formed by dissolving the binder resin in water at a concentration of 5% by mass and particle size distribution is measured by a dynamic light scattering method at 25° C. The binder resin contains a polymer (B) having a structural unit represented by the following Formula (11) and a specific structural unit. The binder resin also contains a polymer (?) having a specific structural unit and a structural unit represented by the following Formula (22), and/or a mixture of a polymer (?1) having a specific structural unit and a polymer (?2) having a structural unit represented by the following Formula (22).

Abstract: The use of a binder resin for a secondary battery electrode which is a polymer characterized by containing, as polymer-constituent monomer units, a vinyl cyanide monomer unit at a ratio of 50 to 99.99% by mole and a phosphoric acid group-containing monomer unit at a ratio of 0.01 to 50% by mole, and preferably having a mass-average molecular weight of 200,000 to 3,000,000 makes it possible to obtain a battery in which the in-battery electrochemical stability of the vinyl cyanide monomer unit is exhibited, while the phosphoric acid group-containing monomer unit exhibits an excellent binding property to a current collector to improve the flexibility of the current collector.

Abstract: A solar cell module is provided with a solar cell, a sealing member embedding the solar cell therein, a front surface protective member, and a back surface protective member. The storage modulus of the sealing member for the temperature range of 20-40° C. is from 6×107 Pa to 1×109 Pa (inclusive), and the average linear expansion coefficient, which is the average of linear expansion coefficients in the length direction and in the width direction when the temperature of the back surface protective member is changed from 20° C. to 25° C., is 40 ppm/° C. or less. A solar cell protective sheet is a laminate wherein an adhesive layer contains a (meth)acrylic polymer including functional groups reactive with carboxyl groups is laminated on the surface of a transparent resin sheet formed from at least one light-transmitting resin material selected from (meth)acrylic resins, polycarbonate resins and fluororesins.
