Organic Main-Chain NLO Polymers. 1. Copolymerization of Bis(arylcarboxaldehyde) and Bis(cyanoacetate) Monomers Via the Knoevenagel Condensation

Abstract

Two monomers, 4-(CO2Et(CN)C=CH(C6H40(CH2)6OH(2) and 4-(CHO)C6H40(CH2) 602CCH2CN (3), both containing NLO-phores, were prepared and polymerized by different methods. The Knoevenagel polycondensation technique provided polymers of good molecular weight and tractable in organic solvents. A series of bis(carboxaldehyde) comonomers were prepared in the study, and copolymerized with CNCH2CO2(CH2)6O2CCH2CN to afford new series of accordion polymers (6) which contains NLO-phores. The copolymers were obtained with molecular weights in the range of 3100 to 30,100. We did not observe Tgs for the copolymers above 10 deg C. (Author)
