Synthesis and characterization of some polymers with applications in non-linear optics I. Polymerization of styrene and methyl methacrylate in the presence of coloured comonomers

摘要

New coloured monomers containing azoic and azomethinic chromophores attached on styrenic or methacrylic structures are typical for non-linear optics applications; the present work describes the possibility of their chemical incorporation in classical polymer matrices. It has been shown that the maximal content of coloured monomers in the copolymer chain is influenced only by their intense activity towards chain transfer. The optical properties of the chromophore present in the coloured monomers are preserved after incorporation in the copolymer chain. Inhibition or retardation phenomena have not been noticed during all copolymerization tests performed.
