摘要：
The optical properties of four comb-shaped polymers of the methacrylic series with different optically anisotropic groups in side chains are studied by the methods of flow birefringence and viscometry. The experimental values of the optical anisotropy are compared with theoretical estimates calculated in terms of the additivity principle of polarizabilities of valence bonds. It is shown the optical properties of comb-shaped polymers significantly depend on the position (even or odd) of optically anisotropic side groups relative to the main chain.
