    摘要： Provided is a method for preparing an asymmetric linear carbonate, the method comprising: subjecting two kinds of different symmetric linear carbonates to a transesterification reaction in the presence of a metal alkoxide catalyst to prepare an asymmetric linear carbonate, wherein the metal of the metal alkoxide is at least one selected from the group consisting of aluminum (Al), magnesium (Mg), germanium (Ge), gallium (Ga), cobalt (Co), calcium (Ca), hafnium (Hf), iron (Fe), nickel (Ni), niobium (Nb), molybdenum (Mo), lanthanum (La), rhenium (Re), scandium (Sc), silicon (Si), tantalum (Ta), tungsten (W), yttrium (Y), zirconium (Zr) and vanadium (V). Also provided is an asymmetric linear carbonate including the metal alkoxide catalyst.

    摘要： A resin composition, a multi-layered film, a backsheet for photovoltaic modules, a method thereof, and a photovoltaic module are provided. The multi-layered film including a coating layer including a fluorine-based polymer has an excellent durability and weather resistance, and also exhibits high interfacial adhesive strength to a substrate since the multi-layered film is formed by coating a cured product of the resin composition including the fluorine-based polymer, an acrylic polymer including a thermosetting functional group, and a heat-curing agent on the substrate. In addition, drying can be performed at a low temperature during the manufacture of the multi-layered film so that the manufacturing costs can be decreased, productivity can be increased, and the deterioration of the product due to heat modification, heat shock, and the like, can be prevented. The multi-layered film can be effectively used as a backsheet for various photovoltaic modules.
