Aromatic polyamides containing chalconyl substituted m-phenylenediamine segments

E. Rusu M. Onciu

Abstract

4'(b-hydroxyethoxy)chalconyl-3,5-diaminobenzoate and three kinds of aromatic dicarboxylic acids were used as monomers in a direct polycondensation reaction for synthesis of some polyamides containing chalconyl units in pendant groups. The presence of these units in the structure of polyamides renders them photoreactive and this property was monitored by UV and IR spectroscopy. The polyamides show good thermal stability, glass transition temperature (Tg) values around 230 C degrees and inherent viscosity in the range of 0.67-0.79 dLg-1.
