摘要
A highly efficient, scalable, three step divergent synthesis of blocked isocyanate-terminated polyurethane dendrimers up to fourth generation (G4) has been developed avoiding the formation of free isocyanate. Amine-terminated polyurethane dendrimers were obtained as complementary functional materials in the second step. The blocked isocyanate moiety possessing easily cleavable blocking agents facilitated the dendrimer construction. Heat-curable adhesives based on G2 dendrimers tested on aluminum plates showed tensile shear strength of 2.41 MPa.
