The graft polyurethane prepolymer includes a polyurethane backbone having at least one macromonomer sidechain covalently bonded or grafted thereto. The term "macromonomer" means an oligomer bearing a terminal moiety having two hydroxyl groups that can copolymerize with monomers to form graft copolymers with pendent, preformed polymer chains. The term "prepolymer" means that the polyurethane backbone is terminated by at least one moisture-reactive group such as an isocyanate group or a silane group. In one example the graft polyurethane prepolymer includes NCO termination and is made by reacting one or more macromonomer(s) bearing a terminal moiety having two hydroxyl groups, one or more polyol(s) and an excess of one or more polyisocyanate(s).

Der Absatz kommt in einem Patent über Klebstoffe vor. Da ich kein Chemiker bin, verstehe ich ehrlich gesagt nur Bahnhof. Kann mir jemand auf die Sprünge helfen?

Besten Dank!
