Patent ID: 8592679

Claim:
An electronic device module comprising: A. At least one electronic device, and B. An encapsulant film having a thickness in the range of from 0.125 to about 1.25 mm, said encapsulant film comprising a polymeric material in intimate contact with at least one surface of the at least one electronic device, the polymeric material comprising a reaction product of at least (1) a polyolefin copolymer with (a) a density of less than about 0.90 g/cc, (b) a melt point of less than about 95 C, (c) a 2% secant modulus of less than about 150 megaPascal (mPa) as measured by ASTM D-882-02, (d) an α-olefin content of at least about 15 and less than about 50 wt% based on the weight of the polymer, (e) a Tg of less than about −35C, and (f) a CDBI of at least about 50%, (2) a vinyl silane in an amount of at least about 0.1 wt% based on the weight of the copolymer; and optionally (3), a co-agent, wherein the co-agent, if present, is present in an amount less than 3% by weight of the polyolefin copolymer wherein the polymeric material has a percent optical transmission of at least 30% at 340 nanometers.
