Title:
ETHYLENE-VINYL ACETATE COPOLYMER RESIN, SHEET MOLDING PREPARED THEREWITH, SOLAR CELL SEALING MATERIAL, SOLAR CELL MODULE, AND METHOD FOR PRODUCING ETHYLENE-VINYL ACETATE COPOLYMER RESIN
Document Type and Number:
Japanese Patent JP2017078136
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide ethylene-vinyl acetate copolymer resin that can reduce shrinkage in heating crosslinkage, improve the production efficiency of a solar cell, suppress yellow discoloration in heating crosslinkage, and prevent decrease in the power generation efficiency of the solar cell, and provide a sheet molding prepared with this ethylene-vinyl acetate copolymer resin, a solar cell sealing material, and a solar cell module.SOLUTION: The present invention provides ethylene-vinyl acetate copolymer resin in which crystallization temperature (Tc) measured by DSC (differential scanning calorimetry) and molecular weight distribution (Mw/Mn) measured by GPC (gel filtration chromatography) satisfy the relationship represented by the following formula (1): 10≤Tc/(Mw/Mn)≤30.SELECTED DRAWING: None
