Abstract: A method of manufacturing an artificial turf includes creating fluid polyurethane mass. The creation including reacting first and second polyols with an isocyanate. The first polyol is a polyether polyol and/or a polyester polyol having at least 2 hydroxyl groups per molecule, the second polyol being polybutadien diol. The isocyanate including isocyanate monomers, isocyanate polymers or isocyanate prepolymers or a mixture thereof, the isocyanate monomers, isocyanate polymers and the isocyanate prepolymers having two or more isocyanate groups per molecule. The method further includes incorporating an artificial turf fiber into a carrier such that a first portion of the fiber protrudes to the front side of the carrier and that a second portion of the fiber is located at the back side of the carrier, adding the fluid polyurethane mass on the back side of the carrier, and hardening the fluid polyurethane mass.
