Abstract:UV‐curable oligomers were synthesized by the reaction of ethylene glycol (EG) or 1,4‐butanediol (BDO) with isophorone diisocyanate (IPDI), and then terminated with hydroxyethyl acrylate (HEA). The chemical structures and molecular weight of the two oligomers were analyzed by Fourier transform infrared spectroscopy (FT‐IR), nuclear magnetic resonance (1H NMR and 13C NMR) and high performance liquid chromatography (HPLC). The obtained UV‐curable oligomers were separately mixed with bisphenol A‐type epoxy acrylat… Show more
