Abstract: In the present disclosure, there is provided a polyethylene in which the high molecular region ratio in the molecular structure is lowered, and the viscosity and melt index are optimized with a narrow molecular weight distribution. Therefore, it is possible to prevent premature cross-linking of chlorinated polyethylene obtained by reacting the polyethylene with chlorine, thereby minimizing a decrease in viscosity even after long-term storage and improving extrusion processability. Further, there is provided a vulcanizable chlorinated polyethylene composition using the polyethylene.
