Preparation of UV-curable long chain dibasic acid modified epoxydiacrylates and their coating properties

A number of saturated long chain dibasic acid modified epoxydiacrylates were synthesized. The UV-curable formulations were prepared with those as oligomers. The physical and mechanical characterizations of the UV-cured films were investigated: the addition of the soft long chain in oligomers caused the remarkable increase of the relative elongation at break.
