Highly functional graft copolymer and method for preparing the same

Abstract

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 α-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.
