Abstract
Comblike polymers (copolymers) of methacrylates with nonlinear optical photochromic chromophores in the side chains are synthesized. An increase in the induced birefringence under laser radiation is studied in poly-n-(fluoroalkyl methacrylates) and their hydrocarbon analogs. It is demonstrated that the chemical structure and composition of polymers (copolymers) affect the rise and decay of the photoinduced birefringence and the stability of the second-harmonic generation signal.
