Abstract: This invention relates to segment copolymer comprising rigid and soft segments wherein the soft segments are doped with a wax. A model polymer of this new type can be synthesized by the free radical copolymerization of methyl methacrylate (MMA) (39 wt %), lauryl, methacrylate (LMA) (10 wt %) and an adduct monomer of glycidyl methacrylate (GMA) and 1-dodecylamine (DDA). Doping with paraffin wax is one suitable approach to obtain the inventive material. The invention further relates to a simple and low-cost process to make these polymers and coatings comprising the polymers. Using the polymer material a coating with a highly icephobic surface can be obtained comprising soft hydrophobic micro domains segregated and stabilized by rigid copolymer on its surface. The icephobic behaviour may find new application in aerospace applications.
