Abstract
The polyethylene according to the present disclosure reacts with chlorine to prepare a chlorinated polyethylene having excellent processability during extrusion with a high tensile strength by implementing a molecular structure having a high content of medium molecular weight, and may also prepare a CPE compound including the chlorinated polyethylene.
Claims20
A polyethylene having an entanglement molecular weight of 9500 g/mol to 13000 g/mol, a melt flow rate ratio (MFRR21, 6/5, a value obtained by dividing the melt index measured at 190° C. under a load of 21.6 kg by the melt index measured at 190° C. under a load of 5 kg in accordance with ASTM D 1238) of 16 to 25, and a molecular weight distribution (Mw/Mn) of 5.5 to 10.
