The present invention relates to a ternary elastomeric copolymer having a long chain branch capable of simultaneously satisfying excellent processability and flexibility (flexibility) and a method for producing the same. The ternary elastomeric copolymer is a copolymer of ethylene, an alpha olefin having 3 to 20 carbon atoms and a diene, i) a weight average molecular weight measured by GPC of 100,000 to 500,000, ii) The reciprocal number y of the melt index (g / 10min) x at 190 ° C and the pattern viscosity (1 + 4 @ 125 ° C, MU) is 0.011x 2 + 0.052x + 0.031 ≤ y ≤ -0.011x 2 + 0.052x + 0.038 can be satisfied. |
