Abstract

A polymeric material, prepared by reacting a mixture comprising a polyorganosiloxane having one or more isocyanate-reactive functional groups, polyisocyanate, and polyol, is provided. The isocyanate-reactive functional groups, typically one or two, are attached to only a single end of the polyorganosiloxane chains. The polymeric material may be used to form coatings on a substrate and to inhibit fouling on surfaces exposed to aqueous conditions.
