| 摘 要： | The viscosity,the shrinkage degree and the photopolymerization rate of the epolxy acrylate(EB600) blended with hyperbranched acrylated aromatic polyester(HAAPE) were investigated.The addition of HAAPE into EB600 largely reduces the viscosity of the blend formulation and the shrinkage degree.For example,EB600 resin with 50% weight fraction of HAAPE has the 1250 cps of the viscosity and 2.0% of shrinkage degree,while the pure EB600 resin has 3000 cps of the viscosity and 10.5% of shrinkage degree.The photopolymerization rate of the resin is also promoted by HAAPE addition.The good miscibility between HAAPE and EB600 was also observed from the dynamic mechanical analysis.The tesile,flexural and compressive strength,and the thermal properties of the UV cured films are greatly improved.

| Abstract: | The viscosity, the shrinkage degree and the photopolymerization rate of the epoxy acrylate (EB600) blended with hyperbranched acrylated aromatic polyester (HAAPE) were investigated. The addition of HAAPE into EB600 largely reduces the viscosity of the blend formulation and the shrinkage degree. For example, EB600 resin with 50% weight fraction of HAAPE has the 1250 cps of the viscosity and 2.0% of shrinkage degree, while the pure EB600 resin has 3000 cps of the viscosity and 10.5% of shrinkage degree. The photopolymerization rate of the resin is also promoted by HAAPE addition. The good miscibility between HAAPE and EB600 was also observed from the dynamic mechanical analysis. The tensile, flexural and compressive strength, and the thermal properties of the UV cured films are greatly improved. |
