Abstract
The hyperbranched polyurethane acrylate oligomers containing photoinitiator were synthesized by modifying the second-generation hyperbranched poly(amine-ester) with isophorone diisocyanate-2-hydroxyethylacrylate and isophorone diisocyanate-2-hydroxy-2-methylpropiophenone at different feed ratio. The elemental analysis, FT-IR and NMR methods are used for structural characterization, molecular weights, and polydispersities, photosensitive groups and thermal properties of the oligomers were analyzed by gel permeation chromatography, UV–Vis spectra and thermogravimetric analysis, respectively. UV-curing properties were characterized by FT-IR at different curing time. In addition, the solubilities of the oligomers were also examined.
