The present invention relates to a polymer for a gel polymer electrolyte and a gel polymer electrolyte and a lithium secondary battery, each comprising same. More specifically, the polymer for a gel polymer electrolyte has a fluorine-based polymer backbone grafted with a siloxane group-bearing side chain and an acryl-based polymer-bearing side chain and can improve stability in the gel polymer electrolyte and the lithium secondary battery, each comprising the polymer for a gel polymer electrolyte. |
