Abstract

The polymerization behavior of acrylate resin has been analyzed and evaluated its mechanical properties such as tensile strength and elongation of the films which are cured by EB irradiation and UV light exposure. The existence of the cross-linkage of the polymer can be found by IR, NMR and the mechanical property measurements. Increasing EB dose causes the great change for the properties of the three dimensional cross-linked cured film. But, there is no difference in the UV system. From these results, we clarified that the films cured by different energy souse such as EB and UV have different properties. Further, it is found that there is a close relationship between the NMR relaxation times and mechanical properties such as tensile strength of the EB irradiation film.
