Photopolymerization technology has attracted a significant amount of attention due to its various industrial applications, such as coatings, paints and printing inks, adhesives, composite and dental remedial materials. In particular, UV-curing system has many advantages like as good chemical and dimensional stability, high productivity in term of cost, quick production rate in small place of work and curing at low temperature. We synthesized a series of carboxylic ester acrylate oligomers as base materials for UV curing resin. The chemical structure of carboxylic ester acrylate oligomers was identified by FT-IR and 1H-NMR measurements. The resin mixtures containing carboxylic ester acrylate oligomer, acrylate monomers and other additive were prepared and their physicochemical properties, such as viscosity, miscibility and glass transition temperature, were investigated. The adhesive properties, thermal stability, transparency as a function of time were also investigated. |
