Blended polymer containing ethylene / tetrafluoroethylene copolymer, molded product of the blended polymer, backsheet for solar cell and method for producing the molded body

摘要

A blended polymer comprising an ethylene / tetrafluoroethylene copolymer having high weather resistance and high heat distortion temperature, a molded article such as the film, a back sheet for a solar cell provided with the film, and a method for manufacturing the molded body. A blended polymer comprising an ethylene / tetrafluoroethylene copolymer and polymethyl methacrylate, wherein the blend polymer comprises ethylene / tetrafluoroethylene, based on the total weight of ethylene / tetrafluoroethylene copolymer and polymethyl methacrylate in the blend polymer A ratio of the mass of the copolymer is 50 to 75%, the continuous phase is an ethylene / tetrafluoroethylene copolymer, and the dispersed phase is polymethyl methacrylate.
