ABSTRACT:
The present invention provides novel heat stable polyamide polymer having excellent flow properties which render them more readily processible into fibers, films, sheets and other molded articles. The polymers are prepared by forming the polycondensation product of one or more aromatic diamines and one or more aromatic dibasic acid monomers or amide-forming derivatives thereof, at least one of said diamine monomers having the structure: ##STR1## where R is CF.sub.3 or phenyl. The polyamides of this invention exhibit improved solubility and low temperature flow characteristics, low moisture uptake, high thermal stability, low dielectric constant and good hydrolytic stability.
