Abstract

The present invention relates to a method of producing an elastomer. Specifically, the method of producing an elastomer according to the present invention comprises a step of polymerizing ethylene, propylene, and optionally, a diene monomer in the presence of a catalyst composition containing a transition metal compound. The method of producing an elastomer according to the present invention makes it possible to prepare a high molecular weight, ethylene-propylene or ethylene-propylene-diene, elastic copolymer at a high temperature.
