摘要： The present invention relates to an encapsulant film composition including an ethylene/alpha-olefin copolymer, an encapsulant film, and a solar cell module.
When an encapsulant film is produced using the encapsulant film composition according to the present invention, the immersing time of an ethylene/alpha-olefin copolymer is reduced so that the economic viability of a process of producing an encapsulant film can be improved. In addition, the encapsulant film composition produced by using the present invention exhibits excellent crosslinking degree.-

摘要： The present invention relates to a method of preparing a graft polymer, which includes: preparing a second diene-based rubber polymer by enlarging a first diene-based rubber polymer with an acidic group-containing acrylic polymer; preparing a first mixture comprising the second diene-based rubber polymer and a non-ionic emulsifier; and preparing a graft polymer latex by polymerizing an aromatic vinyl-based monomer and a vinyl cyanide-based monomer in the presence of the first mixture.
