Abstract
Thin films were prepared with urethane acrylate oligomer in combination with a number of acrylate monomers. Two monofunctional monomers such as 2-ethylhexyl acrylate (EHA) and N-vinylpyrrolidone (NVP); two difunctional monomers, e.g., hexanediol diacrylate (HDDA) and tripropylene glycol diacrylate (TPGDA); and a trifunctional monomer, trimethylol propane triacrylate (TMPTA), were used to prepare the films. These were cured under UV radiation. Their physicomechanical properties were studied. TMPTA film showed the highest hardness with the least tensile properties (tensile strength and elongation at the break). However, NVP exhibited the best performance among all these functional monomers as far as physicomechanical properties are concerned.
