Paper Abstract

We report the results of a temperature study of the optical Kerr effect in 1,4-butanediol dimethacrylate revealing a phase-transition-like change in the temperature range from 295 to 302 K. Using the Brillouin light-scattering method, we studied the temperature behavior of the sound velocity and the elasto-optic constant of 1,4-butanediol dimethacrylate. The preceding temperature dependences display also characteristic discontinuity at about 298 K. To verify these results, a study of the Raman light scattering in 1,4-butanediol dimethacrylate was performed in the same temperature range. It was found that the temperature dependence of the relative intensities of the bands corresponding to the C = C, C = 0, and = C-H bonds reveals a discontinuity at about 294 to 297 K, which coincides with the observed temperature discontinuity of the optical Kerr effect and the Brillouin light scattering. The obtained results are discussed in terms of changes in molecular interactions and the arrangement in the liquid compound investigated.
