example

[0107] A multimetallic catalyst was prepared and used to prepare the inventive vinyl polymer (Inv. EBP) in solution polymerization. The vinyl polymers of the present invention are used to prepare the artificial turf filaments of the present invention. Tests were performed on vinyl polymer and artificial turf filaments.

[0108] Catalyst preparation of the present invention

[0109] 7.76 kg EADC solution (15 wt% in heptane) was added to about 109 kg 0.20M MgCl 2 slurry, followed by stirring for 8 hours. Subsequently, adding TiCl 4 / VOCl 3 (85mL and 146mL, respectively), followed by the addition of Zr(TMHD) 4 (0.320 kg of a 0.30 M solution in Isopar E). These two additions were performed sequentially within 1 hour of each other. The resulting catalyst premix was aged with stirring for a further 8 h before use.

[0110] Vinyl Polymers of the Invention (Inv. EBP)

[0111] All starting materials (ethylene, 1-hexene, 1-octene) and process solvents (isoalkane solvent und...

Abstract

An artificial turf filament comprising an ethylene-based polymer, wherein the ethylene-based polymer comprises greater than 50 wt.% of the units derived from ethylene and less than 30 wt.% of the units derived from one or more alpha-olefin comonomers.

Description

technical field [0001] Embodiments of the present disclosure generally relate to artificial turf filaments, articles incorporating artificial turf filaments, and their manufacture. Background technique [0002] Synthetic or artificial turf is increasingly used as an alternative to natural grass turf for use in stadiums, sports fields, landscaping, and other recreational applications. To make artificial turf, the turf yarns can be extruded and then tufted through the primary backing. The secondary backing can be coated to "glue" the turf yarns to the primary backing. Extruded turf yarns can have different yarn profiles. That is, various turf yarn cross-sectional shapes and / or thicknesses can be used, which can have a dramatic effect on the optical appearance of the yarn as well as its performance during the assembly process and during the life of the artificial turf. [0003] Additionally, during post-extrusion processing, high temperature (>100°C) ovens may be used to ...
