ABSTRACT:
New processable polyaromatic amides were prepared from the acid chloride of bis-m-carboxyphenyl acetylene and several aromatic diamines. The polyamides containing the acetylene units were cured by Diels-Alder cycloaddition reaction with 1,4-diphenyl-1,3-butadiene. Cured polyamides showed increase in Tg. thermal and heat stabilities. The polyamides can be cast into films and give good glass fiber laminates.
