Abstract The present invention relates to a process for manufacturing an ethylene copolymer through copolymerization reaction, extrusion, and granulation processes using a raw material containing ethylene and alpha olefin, and specifically, to a process for manufacturing an ethylene copolymer that is easy to extrude and granulate, which can maintain a strand shape at the rear of an extruder and facilitate extrusion and granulation by lowering the temperature of a copolymer resin input into the extruder in advance. To this end, the present invention relates to a process for manufacturing an ethylene copolymer, including: a preparation step of preparing a raw material containing ethylene and alpha olefin; a copolymerization step of manufacturing a copolymer resin composition by copolymerizing the raw material; a step of removing impurities by passing the manufactured copolymer resin composition through a separation unit, and removing the impurities to manufacture a copolymer resin; an extrusion step of extruding the manufactured copolymer resin by putting the copolymer resin into the extruder; and a granulation step of granulating the extruded copolymer resin, wherein a cooling step before extrusion of lowering the temperature of the copolymer resin before putting the copolymer resin into the extruder is performed. 본 발명은 에틸렌과 알파 올레핀이 포함된 원료를 이용하여 공중합 반응, 압출, 제립 공정을 통해 에틸렌 공중합체를 제조하는 공정에 관한 것으로서, 압출기로 투입되는 공중합체 수지의 온도를 미리 하강시킴으로써 압출기 후미에서 가닥 형태를 유지하고 압출 및 제립이 용이하도록 할 수 있는 압출 및 제립이 용이한 에틸렌 공중합체의 제조 공정에 관한 것이다. 이를 위해 본 발명은, 에틸렌과 알파 올레핀이 포함된 원료를 준비하는 준비단계; 상기 원료를 공중합 반응시켜 공중합체 수지 조성물을 제조하는 공중합 단계; 상기 제조된 공중합체 수지 조성물을 분리유닛을 통과시켜 불순물을 제거하고, 공중합체 수지를 제조하는 불순물 제거 단계; 상기 제조된 공중합체 수지를 압출기로 투입하여 압출하는 압출 단계; 및 상기 압출된 공중합체 수지를 제립하는 제립 단계;를 포함하여 이루어지는 에틸렌 공중합체의 제조 공정에 있어서, 상기 공중합체 수지를 압출기로 투입하기 전 공중합체 수지의 온도를 하강시키는 압출 전 냉각 단계;가 수행되는 것을 특징으로 한다.
