ARTIFICIAL GRASS YARN
An artificial turf comprising a turf yarn prepared from an ethylene-based polymer composition comprising less than or equal to 100 percent by weight of the units derived from ethylene; and less than 30 percent by weight of units derived from one or more ±-olefin comonomers; wherein said ethylene-based polymer composition is characterized by having a Comonomer Distribution Constant of equal to or greater than 40, a vinyl unsaturation of less than 100 vinyls per one million carbon atoms present in the backbone of the ethylene-based polymer composition; a zero shear viscosity ratio (ZSVR) equal to or greater than 1.75; a density in the range of 0.915 to 0.930 g/cm 3 , a melt index (I 2 ) in the range of from 0.8 to 5 g/10 minutes, a molecular weight distribution (M w /M n ) in the range of from 2 to 3.6, and a molecular weight distribution (M z /M w ) equal to or less than 3; and wherein the turf yarn exhibits one or more of the following properties (a) shrink of less than 4.8 %, and (b) curl of less than 0.5 is provided.
