NOVELTY - An electronic device module (10) comprises polymeric material (12) in contact with surface of electronic device (11), where material comprises block copolymer of A block having ethylene and B block having first polymer and tip segments, where segment has at least 5 wt.% of B block and first segment contains ethylene and alpha -olefin and tip segment is polymer of ethylene and alpha -olefin having ethylene content of at least 60 mole%; optionally vinyl silane (at least 0.1 wt.%); optionally free radical initiator or photoinitiator (at least 0.05 wt.%) and optionally co-agent (at least 0.05 wt.%).    USE - As electronic device module such as a solar cell (claimed), photovoltaic (PV) cell module, liquid crystal panels, electroluminescent devices and plasma display units.    ADVANTAGE - The module allows for the use of higher processing temperatures which in turn, allows for faster production rates without unwanted gel formation in the encapsulating polymer due to extended contact with the metal surfaces of the processing equipment.    DETAILED DESCRIPTION - An electronic device module (10) comprises at least one electronic device (11); and a polymeric material (12) in intimate contact with at least one surface of the electronic device, where the polymeric material comprises a block copolymer comprising: A block and B block, where the A block comprises ethylene and the B block includes first polymer segment and tip segment, each of the first polymer and tip segment comprises at least 5 wt.% of the B block, where the first polymer segment is contiguous to a junction of the A block and the B block, where the first segment comprises ethylene and an alpha -olefin, the tip segment is further from the junction, the tip segment is polymer of ethylene and alpha -olefin having an ethylene content of at least 60 mole% based on total moles of monomers of the tip segment, where the ethylene content of tip segment is at least 5 mole% greater than ethylene content of the first portion; optionally a vinyl silane (at least 0.1 wt.% based on the weight of the copolymer); free radical initiator or photoinitiator (at least 0.05 wt.% based on the weight of the copolymer); and optionally a co-agent (at least 0.05 wt.% based on the weight of the copolymer). An INDEPENDENT CLAIM is included for a method of manufacturing the electronic device module involving the step of contacting at least one surface of an electronic device with polymeric material comprising an ethylene-based block copolymer having an A block and B block indicated by a nodular polymer formed by coupling at least two block copolymers.
