The EVA(ethylene-vinyl acetate copolymer)was grafted and modified when acrylic acid(AA),methyl methacrylate(MMA),and γ-methyl acryloyl propyl trimethoxy silane(KH-570)were respectively used asgraft monomers,the influences of graft monomers on some properties(such as crosslinking properties,bondingproperties,transmittance and damp-heat aging resistance)of EVA encapsulants were emphatically discussed. Theresearch results showed that the KH- 570 grafted EVA encapsulant had the relatively best combination prope...
