Using a polyol mixture comprising pbd for creating a pu-based artificial turf

A method of manufacturing an artificial turf, the method comprising:

• creating fluid polyurethane mass, the creation comprising reacting first and second polyols with an isocyanate,
• the first polyol being a polyether polyol and/or a polyester polyol having at least 2 hydroxyl groups per molecule, the second polyol being polybutadien diol;
• the isocyanate comprising 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;
• 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;
• and
• adding the fluid polyurethane mass on the back side of the carrier, the polyurethane mass thereby incorporating at least the second portions of the fiber;
• and
• hardening the fluid polyurethane mass on the back side of the carrier.
