Title Novel Hyperbranched Poly([1,2,3] -triazole)s Derived form AB2 Monomers by a 1,3-Dipolar Cycloaddition
Date 28.06.2004
Abstract Novel hyperbranched poly([1,2,3]-triazole)s were synthesized from several AB2 monomers by a 1,3-dipolar cycloaddition reaction. The compound 3,5-bis(propargyloxy)benzyl azide was polymerized thermally at room temperature leading to 1,4- and 1,5-disubstituted poly([1,2,3]-triazole) and catalytically leading only to the 1,4-disubstituted poly([1,2,3]-triazole). Only the thermal reaction led to fully soluble products. The AB2 monomers containing an internal alkyne A unit could be autopolymerized thermally under mild reaction conditions leading to soluble, high-molecular-weight hyperbranched poly([1,2,3] triazole)s. All products were characterized by detailed NMR investigations.
