ABSTRACT:
Polyamide advanced composites are formed by the condensation of diacid halides (or dicarboxylic acids) and diamines in a linear or multidimensional morphology with crosslinkable end caps that provide improved solvent- resistance. The diamines and diacid halides generally include "sulfone" linkages in aryl chains to impart the desired combination of physical properties to the oligomers, prepregs, and composites. Linear oligomers have mono- or difunctional crosslinking end caps at the ends of polyarylamide chains. Multidimensional oligomers have a hub and three or more radiating amide arms, each arm having a mono- or difunctional crosslinking end cap at its distal end.
