Abstract:
The present invention relates to a highly elastic, ethylene-based quaterpolymer and a preparation method thereof. More particularly, the present invention relates to a highly elastic, ethylene-based quaterpolymer which comprises a specific molar ratio of an ethylene unit, a C4-6 α-olefin unit, a C8-12 α-olefin unit and at least one functional unit derived from a styrene-based monomer and to a method for preparing the ethylene-based quaterpolymer using a metallocene catalyst.
