Synthesis and Photo-Polymerization of Poly(Alkyl Urethane) Acrylate Oligomers Using 2-Isocyanatoethyl Methacrylate for UV Curable Coating

The poly(alkyl urethane) acrylate oligomers (AUAOs) were obtained by the reaction of alkyl acrylate oligomers and 2-isocyanatoethyl acrylate. Synthesis of AUAOs were done with 2-mercaptoethanol (2-MEOH), alkyl (methyl, butyl, 2-ethylhexyl) acrylate, 2,2′-azobisisobutyronitrile (AIBN, initiator) and...

Description
Summary:The poly(alkyl urethane) acrylate oligomers (AUAOs) were obtained by the reaction of alkyl acrylate oligomers and 2-isocyanatoethyl acrylate. Synthesis of AUAOs were done with 2-mercaptoethanol (2-MEOH), alkyl (methyl, butyl, 2-ethylhexyl) acrylate, 2,2′-azobisisobutyronitrile (AIBN, initiator) and dibutyltin dilaurate as a catalyst. Then 2-MEOH was used for functional chain transfer agent. The oligomers were characterized by FT-IR, FT-NMR, rheometer, and DSC. Each oligomer was blended and photopolymerized by UV light, and their ball tack, adhesiveness, and thermal resistance were confirmed by ball tack tester and so on. Photo-polymerized AUAOs can be used for UV curable coatings, inks and adhesives.
