It was investigated the changes of acoustooptical quality coefficients in oI)'goethermethacrylate photopolymers of the different chemical contents from temperature. It was revealed that increasing of the aromatic's rings leads to increasing of the acoustooptical quality coefficients M and only after we have observed the influence of the distances between the C0 chemical bonds. It was found also an increasing of M ith the decrease of the temperature below the 80... 100 K. The maximal value ofthe M reaches its value at 4.2 K. The data obtained are in good agreement with previously investigations of the optical second harmonic generation. An essential influence of external electric field on the acoustooptical properties of the mentioned photopolymers was revealed. In our opinion it reflects an essential role of the acentncal quasicrystallines. which give contributions into the piezooptical constants.
