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 (i) its weight average molecular weight measured by GPC is 100,000 to 500,000, and (ii) x which is an ethylene content (% by weight) and y which is a crystallization temperature (K) of the copolymer measured when the ethylene content is X satisfy a relationship of 2.628x+100≦y≦2.628x+112.
