<P>PROBLEM TO BE SOLVED: To provide a sheet for a solar battery sealing material having adhesiveness, adhesive stability, and heat resistance that are of practical use without cross-linking process substantially and without heat treatment for cross-linking. <P>SOLUTION: A sheet for a solar battery sealing material contains: an ethylene-system copolymer having a melting point of 90°C or higher and which is chosen from the following 1a-5a containing an ethylene originating constitutional unit: and an ethylene-system copolymer chosen from the following 1b-3b whose proportion of glycidyl (meth) acrylate (G(M)A) originating constitutional unit is 2-30 mass%. 1a: an ethylene and vinyl acetate (VA) copolymer, 2a: an ethylene and acrylic acid ester copolymer, 3a: a high-pressure process low-density polyethylene, 4a: an ethylene and α-olefin-system copolymer, 5a: an ethylene and G(M)A copolymer other than the following 1b, 1b: an ethylene and G(M)A copolymer, 2b: an ethylene and VA-G(M)A copolymer, and 3b: an ethylene and acrylic acid ester and G(M)A copolymer. <P>COPYRIGHT: (C)2011,JPO&INPIT |
