| Abstract: | A series of UV curable waterborne polyurethanes based on dimer-fatty-acid polyester diol(PDFA PUs) with different content of C=C were prepared by using isophorone diisocyanate,dimer-fatty-acid polyester diol(PDFA),dimethylol propionic acid and 1,4-butanediol through changing the content of chain extender pentaerythritol diacrylate and using 2-hydroxyethyl acrylate as blocking agent.Fourier transform infrared spectra(FT-IR) confirmed the structural differences of PDFA-PUs before and after UV irradiation.It i... |
