This invention relates to a highly functional graft copolymer and a method of preparing the same, and more particularly, to a highly functional graft copolymer including a main chain of a highly elastic ethylene-based terpolymer including, at a predetermined molar ratio, an ethylene unit, an &#x3b1;-olefin unit having 6 to 12 carbon atoms, and at least one functional unit selected from the group consisting of divinylbenzene and p-methylstyrene, and a side chain of a polar polymer for imparting functionality, and to a method of preparing the highly functional graft copolymer by performing anionic polymerization after catalytic polymerization using a metallocene catalyst.

Highly functional graft copolymer and method for preparing the same

The present invention relates to an ethylene-based terpolymer having high elasticity and a preparation method thereof, and more particularly, to a highly elastic, ethylene-based terpolymer, which comprises a specific molar ratio of a ethylene unit, a C&#x3b1;-olefin unit and at least one functional unit selected from the group consisting of divinylbenzene and para-methylstyrene and to a method of preparing the highly elastic, ethylene-based terpolymer using a metallocene catalyst.
