Organic NLO Polymers. Linear and Accordian Main-Chain NLO Polymers Prepared by aKnoevenagel Polycondensation

摘要

A new main-chain NLO polymer was prepared by transesterification and theKnoevenagel polycondensation. The latter polymer product was obtained as a higher molecular weight polymer with good solubility in organic solvents. New bis(arylcarboxaldehyde) monomers were prepared and copolymerized with bis(cyanoacetate) monomers to afford accordion main-chain NLO polymers. The polymers were characterized by spectroscopic and analytical data, thermal analysis, and GPC.
