Abstract
The present invention relates to a long-chain branched elastic terpolymer capable of satisfying excellent processability and elasticity (flexibility) at the same time, which is obtained in the presence of a Group IV transition metal catalyst, and a preparation method thereof. The elastic terpolymer is a copolymer of ethylene, an alpha-olefin having 3 to 20 carbon atoms, and a diene, wherein
