The synthesis of a series of soluble 5-alkoxy substituted isophthalami
des is described. Condensation of 1,3-diaminobenzene or 2,6-diaminopyr
idine with alkoxy substituted isophthaloylchlorides yields the title p
olyaramides. The influence of the alkyl chain length on the supramolec
ular structure of the polymer is investigated by X-ray diffraction exp
eriments. Initial results indicate a lamellar type solid lattice for t
he polymers studied here.
