LOW DENSITY POLYETHYLENE RESIN WITH ECELLENT PROCESSABILITY AND PREPARATION METHOD THEREOF

摘要

The present invention relates to a low-density polyethylene resin, and more specifically, to a low-density polyethylene resin excellent in processability and a method for producing the same. The low-density polyethylene resin according to the present invention has a relatively high MWD in a low molecular weight region, and is excellent in processability due to an adequate balance of extrusion processing characteristics, neck-in characteristics and drawdown characteristics by melt tension, and therefore, for extrusion coating or lamination. It can be usefully used. In addition, the method of manufacturing a low-density polyethylene resin according to the present invention includes a multi-process in which an autoclave process and a tubular process are sequentially performed, so that the MWD of the low-density polyethylene resin is increased as much as possible, and the high molecular weight region is reduced by the modifier. Since the control range can be widened, MWD control is easy, and process sensitivity is reduced, so processability and productivity are improved compared to autoclave or tubular single processes.
