Beschreibung
Zusammenfassung:	The invention relates to a method of manufacturing an artificial turf (600,the method comprising: -creating (102) fluid polyurethanemass (210), the creation comprising reacting first and second polyolswith an isocyanate, the first polyolbeing apolyether polyol and/or a polyester polyolhaving at least 2 hydroxyl groups per molecule, the second polyolbeing polybutadiendiol; the isocyanate comprising isocyanate monomers, isocyanate polymers or isocyanate prepolymersor a mixture thereof, the isocyanate monomers, isocyanate polymersandthe isocyanate prepolymers having two or more isocyanate groups per molecule; -incorporating (104) an artificial turf fiber (501) into a carrier (308) such that a first portion (302) of the fiber protrudes to the front side of the carrier and that a second portion (506) of the fiber is located at the back side of the carrier; and -adding (106) the fluid polyurethanemass on the back side of the carrier; and -hardening (108) thefluid polyurethane mass.
