Abstract
The present invention relates to an elastic terpolymer which can satisfy excellent processability and elasticity (flexibility) at the same time, and a preparation method thereof. The elastic terpolymer is a copolymer of 40 to 70 weight % of ethylene, 15 to 55 weight % of a C3-C20 alpha-olefin, and 0.5 to 20 weight % of a diene obtained in the presence of a group 4 transition metal catalyst, of which i) the weight average molecular weight measured by GPC is 100,000 to 500,000, and ii) Δ tan δ, the difference between the tan δ values at the angular frequencies of 0.2 rad/s and 100.0 rad/s, is 0.5 or less that is measured at 100° C. by using a rubber process analyzer.
