چکیده انگلیسی
Polyurethane acrylates (PUAs) modified by saturated alcohols were synthesized by saturated alcohols, isophorone diisocyanate (IPDI), 2-hydroxyethyl acrylate (HEA) and polycaprolactone triol (PCL). The molecular structures were identified by Fourier transform infrared (FTIR) spectroscopy. Real time infrared (RTIR) spectroscopy was used to investigate the conversion vs. irradiation time plots of photopolymerization of synthesized PUAs. The volume shrinkage was measured by using laser displacement sensor (LDS). The adhesion in the glass, polycarbonate (PC) and polyvinyl chloride (PVC) substrates was tested by the laser micrometer and universal testing machine. The glass-transition temperature (Tg) and storage modulus (Eâ²) were measured by dynamic mechanical analysis (DMA). The pendulum hardness, pencil hardness and flexibility were also tested. The results showed that the synthesized PUAs had low volume shrinkage and excellent adhesion in glass, PC and PVC substrates.
