The invention relates to polyethylene and a preparation method thereof. More specifically, the present invention relates to a polyethylene having a low melt index, a narrow molecular weight distribution, and a high content of high molecular weight components, thereby exhibiting excellent ESCR and tensile strength, and a method for preparing the same. 本发明涉及聚乙烯及其制备方法。更具体地，本发明涉及具有低熔体指数、窄分子量分布和高含量的高分子量成分从而表现出优异的ESCR和拉伸强度的聚乙烯及其制备方法。
