Crystalline adducts of the polyamides: poly-e-caproamide, poly(hexamethylene adipamide), poly-p-benzamide, poly(p-benzanilidene terephthalamide), and mixtures thereof; with the perfluorinated diacids: perfluorosuccinic acid, perfluoroglutaric acid, perfluoroadipic acid, and mixtures thereof. The polyamide components of the adducts contain at least 25 about amide groups in the polymer chain, preferably at least 75 amide groups for aliphatic polyamides and at least 50 amide groups for aromatic polyamides. The adducts can be formed into shaped objects from which diacid can be leached to produce a porous object useful for example as a filtration device.

A method and reagent for the selective nitration of aromatic hydrocarbons which comprises contacting a complex of at least a catalytic amount of a polyether with a nitronium containing substance, e. g. , NO. sub. 2 BF. sub. 4 with an aromatic hydrocarbon, e. g. , toluene with at least one replaceable hydrogen. Nitration of toluene with these complexes at ambient temperature resulted in a reduction in meta substitution. In competitive studies, soluble crown ether complexes of NO. sub. 2 BF. sub. 4 in CH. sub. 2 Cl. sub. 2 nitrated toluene 45-59 times faster than they nitrated benzene.
