The present invention provides a method for providing anti-ice protection to surfaces, particularly aerodynamic surfaces, to prevent foul weather icing for extended periods of time and over repeated icing situations, comprising applying an organic polymer matrix layer to the surface where the organic polymer matrix layer comprises a homopolymer comprising up to 50% porous polymer solids having a pore size of up to 100 Angstroms and being capable of absorbing and chemically bonding an aqueous freeze-point depressant solution in amounts of up to 99.75% by weight.
