Abstract
Although the fibers of poly(p-phenylene terephthalamide) (PPTA or Kevlar), poly{(benzo-[1,2-d;4,5-d']-bisoxazole-2,6-diyl) -1, 4-phenylene} (PBZT) and poly{(benzo-[1,2-d;4,5-d']-bisoxazole-2, 6-diyl)-1,4-phenylene} (PBZO) are extremely stiff, tough, and are strong in tension they remain relatively weak in compression. We have developed a way of introducing lateral covalent bonding into the backbone of condensation polymers by means of the thermally-activated cross-linking agent, 1,2-dihydrocyclobutabenzene 3,6-dicarboxylic acid (XTA). Here we present the synthesis and physical characterization of PPTA copolymers with varying mole % XTA (PPXTA). DSC and TGA analyses are also presented.
