Dendritic polymers have received increasing interests from polymer scientists because of the unique structural characteristics, synthetic methods as well as application fields. The (meth)acrylated dendritic poly(ether amide)s were synthesized by a divergent manner and characterized by 1H NMR, VPO and FTIR measurements. Their UV curing properties were investigated by Raman, Photo DSC and DMTA measurements. Over 80% of unsaturation conversion has been obtained for the systems in the presence of a photoinitiator under UV irradiation, and the polymerization rate at peak maximum was promoted with increasing the concentration of double bonds. The softening and glass transition temperatures of their UV cured films were also promoted with increasing the concentration of double bonds.
