Birefringence in polymers degrades the performance of optical devices. We focused on photoelastic birefringence, and proposed two methods of compensating for the birefringence - the random copolymerization method and the anisotropic molecule dopant method. Furthermore, we measured IR dichroism of methacrylic polymers which have various photoelastic coefficient. From the results of the IR dichroic ratio, we estimated that C=O bond moved in the perpendicular direction to the drawing direction and C-O-C bond moved in the parallel direction. Photoelastic coefficients of methacrylic polymers depends on the contribution to optical anisotropic by the motion of C=O and C-O-C bonds.
