There is provided a polymeric material prepared by reacting a mixture comprising a polyorganosiloxane having at least one isocyanate-reactive functional group, a polyisocyanate, and a polyol. Typically one or two, isocyanate-reactive functional groups are attached only to a single end of the polyorganosiloxane chain. Polymeric materials can be used to form a coating on a substrate and to inhibit fouling on surfaces exposed to aqueous conditions. |
