Abstract
Polymeric compositions useful in preventing the frost or ice deposition in the surface of wind turbine generator blades present in a cold climates or high altitude are provided. In addition to the anti-icing capacity, the polymeric composition prevents the deposition of dirt, i.e. it has self-cleaning properties.
