Abstract
An encapsulant composition containing about 15 to about 50 wt % of an ethylene/ethyl acrylate/maleic anhydride copolymer containing about 20 to about 40 wt % of an ethylene/glycidyl (meth)acrylate copolymer; about 2 to about 30 wt % of an ethylene/butyl acrylate/maleic anhydride copolymer; about 5 to about 50 wt % of polyethylene, about 0.05 to about 5 wt % of an adhesion promoter; and optionally about 0.01 to about 2 wt % of at least one additive. The composition is useful for encapsulating thin film devices. The disclosure also relates to a method of encapsulating thin film devices with the composition and to devices produced by the method.
