摘要：
Platinum acetylacetonate was encapsulated within polyurea microcapsules and utilized in the hydrosilylation of acetylenes after treatment with hydrogen. The encapsulation process is based on the emulsification of dichloromethane containing Pt(acac)2 and polyisocyanate monomer in water followed by interfacial polyaddition reaction that occurs after adding diamine monomer to the emulsion. The resulting catalytic microcapsules were characterized by SEM, solid NMR, TGA and FT-IR spectroscopy.
