Title: From rosin to high adhesive polyurethane acrylate: Synthesis and properties
Abstract: A high adhesion polyurethane acrylate (HPUA) was synthesized from isophorone diisocyanate (IPDI), hydroxyethyl acrylate (HEA) and hydrogenated rosin. The chemical structure was characterized by 1H NMR and FTIR; storage modulus and glass transition temperature (Tg) were measured with dynamic mechanical analyzer. Real time infrared spectroscopy (RTIR) was used to investigate the effect of different concentrations of photoinitiator on the double bond conversion of HPUA. Real time volume shrinkage and adhesion on glass, poly(ethylene terephthalate) (PET), polycarbonate (PC) and polyvinyl chloride (PVC) substrates were also measured by laser micrometer and universal testing machine. Results showed that this kind of HPUA has a high photopolymerization rate, low volume shrinkage and high adhesion compared with commercial polyurethane acrylate competitor.
