A polymer electrolyte for use in a lithium secondary battery prepared by polymerizing a composition including 0.1 to 90% by weight of a first compound represented by formula 1, a second compound represented by formula 2 or a mixture thereof, 0.1 to 90% by weight of a third compound represented by formula 3, and 9.8 to 99.8% by weight of a nonaqueous organic solvent containing 0.5 to 2.0 M of a lithium salt. Formula 1 is CH(R1)=C(R2)-C(=O)O-R3-N(R4)(R5), Formula 2 is CH(R1)=C(R2)-C(=O)O-R3-CN, and Formula 3 is Z-{-Y-X-C(R2)=CH(R1)}n.
