Several nonlinear optical polymers containing azometine side-chain groups h
ave been obtained by interfacial polycondensation. The structures of obtain
ed monomers and polymers were confirmed by infrared, H-1-NMR, and ultraviol
et spectroscopies. Mechanical, thermal, and optical properties of the obtai
ned polymers were evaluated. The investigations show that some of the new p
olymers obtained in this study may find use in optical applications. (C) 19
