Beschreibung
Zusammenfassung:	Provided herein are methods of making a reactive particulate material by free radically polymerizing a single-cure resin to produce a polymer, the resin comprising: a reactive blocked polyurethane prepolymer, a reactive blocked polyurea prepolymer, a reactive blocked polyurethane-polyurea copolymer, or a combination thereof, wherein said polymerizing is carried out by dispersive polymerization (e.g., an emulsion, suspension or dispersion polymerization process), to form said reactive particulate material. Methods of use of the reactive particulate material and material sets including the same are also provided.
