RM257 is a photopolymerisable diacrylate mesogen. In its normal way, the polymerization of the diacrylate mesogen is initiated by using UV light. RM257 mesogen have photopolymeriable acrylate endgroups. RM257 molecules form to polymer network.
In this study, we use 632.8 nm HeNe laser to initiate the monomer conversion of RM257. The effects of light intensity, exposure time and temperature of monomer on the rate of polymerization have been studied. The monomer conversion of RM257 is found to have a higher rate when the mesogen in the isotropic phase. On other hand, using a two ¡Vbeen interference pattern, a periodic structure was be produced in the RM257 polymer network. The mesogen has a uniform ordered. To discuss that diacylate effected by holographic light field.
