Alkyl acrylate oligomers were synthesized from 2-mercaptoethanol (2-MEOH), alkyl (methyl, butyl, 2-ethylhexyl) acrylate, 2,2’-azobisisobutyronitrile (AIBN, initiator) and dibutyltin dilaurate as a catalyst. 2-MEOH was used for functional chain transfer agent. The urethane acrylate oligomers were obtained by the reaction of alkyl acrylate oligomers and 2-isocyanatoethyl acrylate. The oligomers were characterized by NMR, FT-IR spectroscopy, GPC and DSC. The urethane acrylate oligomers can be used for UV curable coatings, inks and adhesives. |
