  Abstract

In this study, photo-cuarable urethane methacrylate oligomers were synthesized from polyether type polyol (PP series, GP series), isocyanate (2,4-toluene diisocyanate) and hydroxy acrylate(hydroxypropyl methacrylate). We measured basic property including color, viscosity and refractive index of resulting urethane methacrylate. Also we measured tensile strength, elongation, and Young's modulus after photo curing. Photo curing speed was investigated using photo-DSC (TA instrument). In the case of similar polyol structure, as the molecular weight of polyol is increased, tensile strength, Young's modulus, curing rate were decreased, but elongation was increased. As the number of functionality of urethane methacrylate oligomer is increased, tensile strength, Young's modulus, curing rate were increased, but elongation was decreased.
