Abstract Summary: Novel block copolymers containing aromatic polyamide (aramid) and fluoroethylene segments were synthesized by a two‐step solution polycondensation. This synthetic method could control the chain‐length of aramid segments and these copolymers could have high structural regularity. The number‐average molecular weight ( $\overline M _{\rm n}$ ) of one of these polymers is over 2.0 × 10 4 . Incorporating fluoroethylene segments improves the solubility of the resulting polymer compared with conventional aramids.The synthesis of the fluoroethylene‐aramid block copolymers.
