Abstract
The polyethylene according to the present disclosure has a molecular structure having a narrow particle distribution and a low content of ultra-high molecular weight, so that a chlorinated polyethylene having excellent chlorination productivity and thermal stability may be prepared by reacting the polyethylene with chlorine. And, a PVC composition including the same with improved impact strength may also be prepared.
