Abstract

The present disclosure relates to an FPOSS prepolymer which may be reacted with a reactive coating or a polyisocyanate and/or one or more of a polysiloxane, a polyol, a polyamine and a reactive coating; an FPOSS polyisocyanate prepolymer which may be reacted with one or more of a polysiloxane, a polyol, a polyamine or a reactive coating; and an FPOSS siloxane prepolymer which may be reacted with a polyisocyanate and/or one or more of a polyol, a polyamine or a reactive coating to form cross-linked polymers capable of reducing the ability of ice to adhere to the surface of an object, in particular aircraft or other vehicles, methods of producing the prepolymers and polymers and their use in coating surfaces.
